CMS Performance Bolt-In Roll Bar For Porsche 911T, GT3 & GT3RS This Roll Bar Fits the Following Cars: Porsche 911T, 992.1 with rear seat delete (2023-25) Porsche GT3, 992.1 (2022-24) Porsche GT3RS, 992.1 (2023-25) Note: This roll bar does not fit the Porsche 992.2 GT3 (2025+). That roll bar will be available in Oct 2026. The Premium Roll Bar For Porsche's Latest Track Day Animal The CMS Performance Roll Bar is the strongest, safest, highest quality bolt-in roll bar on the market for the Porsche 992 911T, GT3 and GT3RS (with the exception of our CMS Performance Clubsport Roll Bar!). In designing and building any CMS Performance roll bar, safety and structural rigidity are our primary goals. And the Porsche 992 T/GT3/GT3RS roll bar is no exception. That's why we fully 360o TIG weld 1.75" Docol R8 Advanced High-Strength Steel tubing instead of the inferior 4130 CrMo or even mild steel other roll bar manufacturers use. CMS Performance tailors the Porsche 992 911T/GT3/GT3RS roll bar to use the strongest chassis mounting points. The main roll hoop is X-braced and features a cross bar for mounting racing harness shoulder straps. Attention To Detail Is The Hallmark Of CMS Performance The CMS Performance Roll Bar for the Porsche 992 911T, GT3 and GT3RS features a harness cross-bar that places your racing harness shoulder straps at the proper angle (0° to -20° front-to-back) and distance (as close as possible) to the driver and passenger, regardless of seat position. Our use of high-tech Docol R8 tubing and main-hoop cross bracing gives you an unobstructed rear view without the need for additional braces that add weight, complexity, and obstruct your view. CMS Performance features uniquely designed three-piece rear kickers that bolt to the Porsche 992 911T/GT3/GT3RS rear shock towers (where the factory GT3 Cup Car roll cage mounts). The safest, strongest mounting points, this adds rigidity to the chassis and suspension. The three-piece kicker design is incredibly strong while also being a breeze to install (vs. the typical one-piece design that is usually a nightmare to install). The main roll hoop is mounted to Porsche's steel frame structure beneath the vehicle just like the factory Cup Car cage. Built To Racing Specs, Finished Like A Porsche Designed using the same guidelines as a full racing roll cage and fully 360oTIG welded by our chassis fabricators and master welders, the CMS Performance Roll Bar for the Porsche 992 T, GT3 and GT3RS is unsurpassed for quality, durability, and structural integrity. We professionally powder-coat each CMS Performance Roll Bar in-house to guarantee fit and finish no other manufacturer can achieve. This also lets us use powder coat colors matched to the Porsche GT3 and GT3RS OEM paint colors for a truly customized aesthetic1. We also offer custom technical powder finishes like the amazing Superchrome (pictured above)! Or you can choose a rich satin black if stealth is more your thing. Powder coating any color you choose is included in the price of your CMS Performance Roll Bar. Don't Settle For Anything Less Than The Best Thoughtful engineering and design, superior materials, masterful fabrication, and beautiful custom finishing at an affordable price. That's the CMS Performance way of doing things. Backed by our legendary customer service, it all adds up to this: you can certainly pay a lot more for a roll bar, but you can only get the best from CMS. Add Premium Racing Harnesses To Your Porsche Add six-point Schroth Enduro 2x2 GT3, Schroth Flexi 2x2 GT3, or Sabelt Silver Series GT3 racing harness to your order and save! These harnesses are specifically designed for the Porsche 992 GT3 and GT3RS and will bolt to your factory lightweight carbon bucket seats. Or you can add four-point Schroth Profi II ASM GT3 or Sabelt Porsche GT3 4 Point harnesses, ideal for the Porsche 992 T, GT3 and GT3RS passenger seat that doesn't have a factory sub-strap pass through. With six-point harnesses, we strongly recommend using the CMS Performance Sub Strap Mount to provide a solid, properly located anchor for your anti-submarine straps. The CMS Performance Sub Strap Mount is simple to install at the same time you're installing your roll bar! Straightforward Installation Takes The Headache Out Of Roll Bars Click Here for Installation Instructions We've been through more than a few wrestling matches installing bolt-in roll bars in street cars. Fortunately, we used that experience to design the CMS Performance Roll Bar for the Porsche 992 T, GT3 and GT3RS to be a lot less frustrating to install. We hesitate to go so far as to say it's easy, but we'll say it isn't hard if you have a friend and some basic tools.

CMS Performance Bolt-In Roll Bar For Porsche 981 & 718 Cayman This Roll Bar Fits The Following Cars: 2014-16 (981) Cayman Base, S, GTS, GT4 2017+ (718) Cayman Base, S, GTS, GT4 Hands Down the Best Roll Bar for the Porsche Cayman The CMS Performance Roll Bar is the strongest, safest, and most beautifully constructed roll bar on the market for your Cayman. In designing our roll bar, safety and structural rigidity were our primary goals. That's why we use 1.75 x .095" Docol R8 Advanced High-Strength Steel tubing (harness cross bar is 1.5" to minimize weight), much stronger than the smaller-diameter 4130 CrMo tubing others use. The 1.5" harness cross-bar is designed to put your harness shoulder straps at the proper angle (0° to -20°) and distance to the driver, regardless of your seat position. Yet the CMS roll bar requires no cutting through the carpeted hump in the middle of your interior (replacing this carpet is expensive if you ever want to return your car to stock). This also provides an ideal mount for a SmartyCam video camera. Unsurpassed Design and Meticulous American-Made Craftsmanship Our use of Docol R8 tubing throughout also lets us keep the driver's rear view unobstructed by the rear diagonal bracing typically used to support weaker roll bars. This also gives you unfettered access to the engine cover without removing any part of your roll bar. Other roll bars require partial removal to get at your engine -- not ideal in a car that sees track time. The CMS Performance Roll Bart for the Porsche Cayman features rear kickers bolted to the Cayman's rear shock towers, the safest, strongest possible mounting points. This mounting also adds rigidity to the chassis and suspension for improved handling. The main roll hoop is mounted to the frame structure across the rear bulkhead for lighter weight and superior strength. The Only Roll Bar Color-Matched to Your Porsche CMS Performance has perfected the process of powder coating each roll bar in a color custom-matched to Porsche's OEM color palette1. This gives your Cayman roll bar a truly unique, from-the-factory look. We also offer technical powder coat finishes like the amazing-looking Superchrome! Or you can go with a rich satin black for a more stealthy, low-key installation. Every CMS roll bar is professionally powder-coated to order in-house. Fully TIG welded by master welders using superior materials, the design, strength, fit, and finish of the CMS roll bar all add up to this: you can spend more on a roll bar, but you only get the best from CMS.

Our use of high-tech Docol R8 tubing and main-hoop cross bracing gives you an unobstructed rear view without the need for more extensive braces that roll bars made of Chromoly or mild steel have to use. CMS Performance designed the rear kickers of the Porsche 991 Roll Bar to bolt to the rear shock towers (same as the factory GT3 Cup roll cage). Using the strongest mounting points adds rigidity to the chassis and suspension to improve handling precision. The CMS Performance main roll hoop is mounted to the steel sub-structure beneath the vehicle just like the factory cage. Built Like A Tank, Finished Like A Porsche The CMS Performance Roll Bar for the Porsche 991 is fully TIG welded by master welders giving it unsurpassed structural integrity and a precision fit in the car.

Litespeed Racing VS10 Forged Magnesium Wheel Ten-Spoke Beautifully Sculpted Racing Wheel The Litespeed VS10 Forged Magnesium wheel is one of the lightest and most popular wheels we carry. Litespeed Racing devoted countless hours of FEA computer simulations to fine tuning every aspect of the VS10’s geometry for maximum weight reduction and overall strength, while also maintaining a beautifully sculpted spoke design. The Litespeed Racing VS10 Forged Magnesium wheel is track-proven at race venues across the world, from road courses to autocross to quarter-mile to half-mile top speed races. Starting at just 15 pounds for a 19-inch wheel, in many fitments the Litespeed VS10 will be one of the lightest wheels available in the industry. In fact, the Litespeed VS10 Forged Magnesium monoblock is so light, it's actually lighter than many full carbon fiber wheels. Fully Forged From Magnesium Alloy In a quest to build the lightest wheel possible, Litespeed actually started with the obvious solution: carbon fiber. It's a seemingly magical material, with super-high tensile strength and super-low density. But the resulting wheel was not as light as expected, mainly because a lot of carbon needs to be added to make it safe enough to withstand impacts. Also, carbon fiber can't be formed into strong complex shapes like I-beams. Forged magnesium is the solution to these problems. Modern forged magnesium alloys are light years ahead of the old school “mag” wheels made from cast magnesium. Litespeed Racing’s proprietary forged magnesium alloy actually outperforms forged aluminum in both tensile strength and fatigue strength, while being a naturally lighter material. The result is forged magnesium monoblock wheels that, in many cases, are actually lighter than some OEM full carbon fiber wheels of the same size. Every Litespeed Racing wheel is custom made to fit your specifications for size, offset, color, finish, brake clearance and load rating. Once you've made your purchase, give us a call at (844) 438-7244 to select the specs, color and finish that suit your application!

Litespeed Racing RS5RR Forged Magnesium Wheel Ultra-Lightweight Magnesium Alloy Monoblock Racing Wheel The RS5RR is Litespeed's newest and most exciting version of the RS5, their lightest and most popular wheel style. Fully forged from Litespeed's magnesium alloy, the RS5RR is lighter and stronger than similar wheels made from forged aluminum. In fact, countless hours of FEA computer simulations where employed to fine tune every aspect of the RS5RR’s geometry, maximizing weight reduction with specially-engineered hollowed spoke pockets. Like the RS5 before it, the RS5RR racing wheel is competition-proven on tracks across the world, from road courses to autocross to quarter-mile and half-mile top speed races.

Advanced Cooling, Superior Bite, Unmatched Durability At the heart of every rotor is AP Racing’s proprietary high-carbon iron alloy, developed to withstand repeated thermal cycling without cracking or warping. Internally, directional vanes—far superior to OEM pillar or straight vane designs—maximize airflow and cooling. With 60 to 84 vanes per rotor, AP Racing achieves faster heat evacuation, reduced brake fade, and a more consistent friction surface. These rotors are left/right-specific for optimal airflow and balance. The exclusive J Hook slot pattern offers enhanced initial bite and promotes uniform heat distribution across the rotor face, reducing pad deposits and vibration. Unlike drilled rotors or straight-slot competitors, the J Hook design provides cleaner pad transfer during bed-in and superior modulation under braking—ideal for serious drivers who demand feedback and control. Yes, you might hear a little more whirr, but you’ll gain the stopping power, consistency, and longevity your lap times demand. Premium Components, Affordable Performance The rotor hats are CNC-machined from 6061-T6 billet aluminum and hard anodized for strength and heat resistance. Scalloped edges under the hat further assist heat dissipation. All hardware is U.S.-made to AP Racing spec, the same quality found on pro-level racing platforms. And while these rotors are race-proven, they’re also surprisingly cost-effective to replace. Don’t settle for cheap rotors that crack after a weekend—AP’s J Hook rings offer better durability and real long-term value. Fewer replacements mean more track time, less downtime, and peace of mind knowing you're running the best. Used by Champions. Trusted by Experts. From endurance racers to HPDE enthusiasts, AP Racing brake rotors are trusted worldwide for their reliability, longevity, and performance under pressure. Whether you're shaving seconds off your lap time or building a dedicated track car, the J Hook delivers a professional-grade solution that won’t let you down.   AP Racing J Hook Brake Rotors for Auto Racing, Track Days & HPDE Why Rotor Design Matters: Heat Expansion and Floating Technology As with most metals, iron brake discs expand significantly under heat. When temperatures rise, the disc grows radially—expanding in both diameter and circumference. Traditional one-piece rotors struggle to accommodate this natural expansion. As the outer edge pulls away from the center under heat stress, it creates a condition called “coning”—a distortion that compromises pad-to-rotor contact. This distortion can lead to uneven pad wear, brake tapering, and an inconsistent, long brake pedal. AP Racing two-piece floating brake rotors are purpose-built to eliminate these issues. Engineered with “float” built into the disc or hat assembly, these rotors feature oblong-shaped mounting holes that allow the hardware to slide as the disc heats up. This flexibility ensures the disc runs true within the caliper under high-temperature loads, effectively reducing distortion, minimizing pad taper and stress cracks, and promoting longer component life. Custom Mounting Hardware & Anti-Knockback Spring Clips AP Racing rotors utilize application-specific, U.S.-made mounting hardware—not generic bolts. These premium components are the exact parts used in AP’s professional motorsport products, engineered to withstand the rigors of competitive racing. To manage lateral disc motion that can push caliper pistons backward (known as knockback), AP Racing integrates anti-knockback spring clips on alternating bobbins—five on a ten-bolt setup, six on a twelve-bolt disc. These clips keep the aluminum hat and iron disc ring properly aligned while still allowing for radial float. Bonus: they eliminate annoying rattles and vibrations, ensuring a quieter, more refined braking experience. High-Performance Hat Design for Heat Isolation The disc hats in AP Racing’s two-piece floating rotors are CNC-machined from 6061-T6 billet aluminum and finished with a hard anodized coating. This high-strength aluminum alloy was selected for its ability to maintain structural integrity even at elevated temperatures. AP adds scalloped channels beneath the hat to further encourage airflow and heat evacuation from the outer disc face, minimizing thermal transfer to hubs and wheel bearings—helping reduce maintenance costs on these expensive components. Internal Vane Engineering: Airflow Optimization & Thermal Stability AP Racing’s internal vane design sets them apart from OEM and most aftermarket competitors. While many factory brake discs use non-directional pillar vanes (low-cost and NVH-focused), AP Racing rotors use directional vanes engineered for maximum airflow. These rotors are side-specific—meaning you’ll receive a unique left and right disc in each set—ensuring optimized cooling through strategic vane orientation and shape. Beyond that, AP Racing rotors feature a superior vane count, typically ranging from 60 to 84 vanes, compared to 30–48 in most aftermarket rotors. After extensive CFD and thermal analysis, this high vane count was proven to: Increase airspeed and thermal transfer Reduce recirculation and deflection at the disc face Minimize coning, cracking, and brake fade Deliver more even pad contact and extended rotor life J Hook Slot Pattern: Exclusive to AP Racing Slots and drill holes may improve initial bite, but they also introduce “cool spots” in the rotor face—areas of uneven heating that can lead to stress risers, cracks, and pad vibration. OEM rotors often avoid this by leaving the disc face blank, but that compromises bite and brake feel. AP Racing’s patented J Hook design, developed through rigorous R&D, solves this problem. The hooks are meticulously spaced around the disc’s circumference and from hat to edge, forming a continuous distortion path that ensures even heat distribution. This encourages uniform pad deposits during bed-in, helps reduce judder and cracking, and improves consistency under repeated high-load braking. In addition, the J Hook slots provide more leading edges for pads to grip than traditional curved slots or blank rotors. While this might generate a mild whirring sound during braking, the benefits—more bite, cleaner bedding, better pedal feel—make it the top choice for committed racers and serious track day drivers. Metallurgy Backed by 50+ Years of Motorsport Leadership AP Racing's reputation is built on performance, and their proprietary iron alloy used in J Hook rotors is no exception. Drawing from over five decades of elite motorsport experience, including 750+ Formula 1 wins and widespread use across NASCAR, AP’s engineers have developed a disc alloy that excels under sustained racing temperatures and stress. Where OEM discs focus on affordability and mass production, AP Racing’s J Hook rotors are purpose-built for motorsport durability and heat resistance. Affordable Replacement Cost: Serious Value for Serious Drivers Even the best brake rotors are consumables. When you drive hard—especially at the track—your discs will eventually wear out. That’s why AP Racing designed their replacement iron rings to be cost-effective, allowing you to replace worn parts without breaking the bank. Compare that to constantly buying cheap $150 rotors every weekend—rotors that can't handle the heat and need to be swapped frequently. With AP Racing’s J Hook rotors, you get longer service intervals, less downtime, and better performance over time, making them an incredibly smart long-term investment. Proven on Track. Trusted by Champions. Top-tier racing teams rely on AP Racing J Hook rotors for one reason: they perform under pressure. Whether you're running time trials, attending HPDE events, or competing in wheel-to-wheel racing, these rotors offer professional-grade reliability, safety, and performance. Bedding and preparation of AP Racing J Hook Disc Properly preparing your new brake discs before heavy use is extremely important. The goal of bedding-in your brake pads and discs is to mate them together properly and prepare them for heavy use.  When prepared properly, or bed-in, your pads will transfer a thin layer of material to the disc face (transfer layer).  The pads in your caliper will then actually ride on that thin layer of pad material you’ve put down on the rotor, rather than rubbing directly on the iron rotor face.  A good transfer layer is going to give you superior brake pedal feel, less noise, superior pad wear, and lower the chances of cracking your discs. Important Notes- PLEASE READ! First, make sure you are on a closed course to perform a proper bed-in.  Do NOT perform the procedure on public roads.  You need a stretch of asphalt with long straights, good visibility, and no potential obstructions.  Make sure you are in a position to safely and repeatedly attain the necessary speeds to perform the bed-in procedure.  A controlled racetrack is the best place to perform this procedure.  AP Racing and Competition Motorsport in no way suggest or condone speeding on public roads or breaking the law in your car, nor do we take responsibility for any damage or injury that occurs as a result of using our product or these procedures.  You are performing the bed-in procedure at your own risk.  During these procedures, it’s critical that you never come to a complete stop with your foot on the brake pedal.  If you have brake ducts on your car, you may want to block them off to allow your brake system to heat up easily. The procedure outlined below is a generic procedure for most types of mild race pad.  Please check your pad manufacturer’s recommended bed-in procedure. Accelerate to approximately 60mph and then decelerate down to 5 mph.  If your car has ABS, you should try to hold the brakes at a point just before ABS intervention.  Once the car slows to 5mph, immediately accelerate back up to about 60mph, and brake again to roughly 5mph.  Repeat this series of stopping and accelerating 8 to 10 times.  Again, do not come to a complete stop with your foot on the brake pedal. Cool the brake system down by cruising at 45mph+ for 5 to 10 minutes. Visually inspect your discs.  They should be a blue/grey color (instead of shiny silver), and have an even layer of pad material across and around the entire rotor face. If the AP Racing rotors don’t have a layer of pad material on them, perform another series of stops in the manner outlined above.

Cool the brake system down by cruising at 45mph+ for 5 to 10 minutes. Visually inspect your discs.  They should be a blue/grey color (instead of shiny silver), and have an even layer of pad material across and around the entire rotor face. If the AP Racing rotors don’t have a layer of pad material on them, perform another series of stops in the manner outlined above.

Fewer replacements mean more track time, less downtime, and peace of mind knowing you're running the best. Used by Champions. Trusted by Experts. From endurance racers to HPDE enthusiasts, AP Racing brake rotors are trusted worldwide for their reliability, longevity, and performance under pressure. Whether you're shaving seconds off your lap time or building a dedicated track car, the J Hook delivers a professional-grade solution that won’t let you down.   AP Racing J Hook Brake Rotors for Auto Racing, Track Days & HPDE Why Rotor Design Matters: Heat Expansion and Floating Technology As with most metals, iron brake discs expand significantly under heat. When temperatures rise, the disc grows radially—expanding in both diameter and circumference. Traditional one-piece rotors struggle to accommodate this natural expansion. As the outer edge pulls away from the center under heat stress, it creates a condition called “coning”—a distortion that compromises pad-to-rotor contact. This distortion can lead to uneven pad wear, brake tapering, and an inconsistent, long brake pedal. AP Racing two-piece floating brake rotors are purpose-built to eliminate these issues. Engineered with “float” built into the disc or hat assembly, these rotors feature oblong-shaped mounting holes that allow the hardware to slide as the disc heats up. This flexibility ensures the disc runs true within the caliper under high-temperature loads, effectively reducing distortion, minimizing pad taper and stress cracks, and promoting longer component life. Custom Mounting Hardware & Anti-Knockback Spring Clips AP Racing rotors utilize application-specific, U.S.-made mounting hardware—not generic bolts. These premium components are the exact parts used in AP’s professional motorsport products, engineered to withstand the rigors of competitive racing. To manage lateral disc motion that can push caliper pistons backward (known as knockback), AP Racing integrates anti-knockback spring clips on alternating bobbins—five on a ten-bolt setup, six on a twelve-bolt disc. These clips keep the aluminum hat and iron disc ring properly aligned while still allowing for radial float. Bonus: they eliminate annoying rattles and vibrations, ensuring a quieter, more refined braking experience. High-Performance Hat Design for Heat Isolation The disc hats in AP Racing’s two-piece floating rotors are CNC-machined from 6061-T6 billet aluminum and finished with a hard anodized coating. This high-strength aluminum alloy was selected for its ability to maintain structural integrity even at elevated temperatures. AP adds scalloped channels beneath the hat to further encourage airflow and heat evacuation from the outer disc face, minimizing thermal transfer to hubs and wheel bearings—helping reduce maintenance costs on these expensive components. Internal Vane Engineering: Airflow Optimization & Thermal Stability AP Racing’s internal vane design sets them apart from OEM and most aftermarket competitors. While many factory brake discs use non-directional pillar vanes (low-cost and NVH-focused), AP Racing rotors use directional vanes engineered for maximum airflow. These rotors are side-specific—meaning you’ll receive a unique left and right disc in each set—ensuring optimized cooling through strategic vane orientation and shape. Beyond that, AP Racing rotors feature a superior vane count, typically ranging from 60 to 84 vanes, compared to 30–48 in most aftermarket rotors. After extensive CFD and thermal analysis, this high vane count was proven to: Increase airspeed and thermal transfer Reduce recirculation and deflection at the disc face Minimize coning, cracking, and brake fade Deliver more even pad contact and extended rotor life J Hook Slot Pattern: Exclusive to AP Racing Slots and drill holes may improve initial bite, but they also introduce “cool spots” in the rotor face—areas of uneven heating that can lead to stress risers, cracks, and pad vibration. OEM rotors often avoid this by leaving the disc face blank, but that compromises bite and brake feel. AP Racing’s patented J Hook design, developed through rigorous R&D, solves this problem. The hooks are meticulously spaced around the disc’s circumference and from hat to edge, forming a continuous distortion path that ensures even heat distribution. This encourages uniform pad deposits during bed-in, helps reduce judder and cracking, and improves consistency under repeated high-load braking. In addition, the J Hook slots provide more leading edges for pads to grip than traditional curved slots or blank rotors. While this might generate a mild whirring sound during braking, the benefits—more bite, cleaner bedding, better pedal feel—make it the top choice for committed racers and serious track day drivers. Metallurgy Backed by 50+ Years of Motorsport Leadership AP Racing's reputation is built on performance, and their proprietary iron alloy used in J Hook rotors is no exception. Drawing from over five decades of elite motorsport experience, including 750+ Formula 1 wins and widespread use across NASCAR, AP’s engineers have developed a disc alloy that excels under sustained racing temperatures and stress. Where OEM discs focus on affordability and mass production, AP Racing’s J Hook rotors are purpose-built for motorsport durability and heat resistance. Affordable Replacement Cost: Serious Value for Serious Drivers Even the best brake rotors are consumables. When you drive hard—especially at the track—your discs will eventually wear out. That’s why AP Racing designed their replacement iron rings to be cost-effective, allowing you to replace worn parts without breaking the bank. Compare that to constantly buying cheap $150 rotors every weekend—rotors that can't handle the heat and need to be swapped frequently. With AP Racing’s J Hook rotors, you get longer service intervals, less downtime, and better performance over time, making them an incredibly smart long-term investment. Proven on Track. Trusted by Champions. Top-tier racing teams rely on AP Racing J Hook rotors for one reason: they perform under pressure. Whether you're running time trials, attending HPDE events, or competing in wheel-to-wheel racing, these rotors offer professional-grade reliability, safety, and performance. Bedding and preparation of AP Racing J Hook Disc Properly preparing your new brake discs before heavy use is extremely important. The goal of bedding-in your brake pads and discs is to mate them together properly and prepare them for heavy use.  When prepared properly, or bed-in, your pads will transfer a thin layer of material to the disc face (transfer layer).  The pads in your caliper will then actually ride on that thin layer of pad material you’ve put down on the rotor, rather than rubbing directly on the iron rotor face.  A good transfer layer is going to give you superior brake pedal feel, less noise, superior pad wear, and lower the chances of cracking your discs. Important Notes- PLEASE READ! First, make sure you are on a closed course to perform a proper bed-in.  Do NOT perform the procedure on public roads.  You need a stretch of asphalt with long straights, good visibility, and no potential obstructions.  Make sure you are in a position to safely and repeatedly attain the necessary speeds to perform the bed-in procedure.  A controlled racetrack is the best place to perform this procedure.  AP Racing and Competition Motorsport in no way suggest or condone speeding on public roads or breaking the law in your car, nor do we take responsibility for any damage or injury that occurs as a result of using our product or these procedures.  You are performing the bed-in procedure at your own risk.  During these procedures, it’s critical that you never come to a complete stop with your foot on the brake pedal.  If you have brake ducts on your car, you may want to block them off to allow your brake system to heat up easily. The procedure outlined below is a generic procedure for most types of mild race pad.  Please check your pad manufacturer’s recommended bed-in procedure. Accelerate to approximately 60mph and then decelerate down to 5 mph.  If your car has ABS, you should try to hold the brakes at a point just before ABS intervention.  Once the car slows to 5mph, immediately accelerate back up to about 60mph, and brake again to roughly 5mph.  Repeat this series of stopping and accelerating 8 to 10 times.  Again, do not come to a complete stop with your foot on the brake pedal.

Spectacular carbon fiber replacements for the black plastic engine bay on the Lamborghini Urus. The quality, beauty, fit, and finish of C3 Carbon for your Lamborghini is unsurpassed. Unlike many competitors, C3 Carbon autoclaves pre-impregnated (pre-preg) dry carbon fiber -- not carbon over fiberglass -- bringing you true factory-level pieces at an affordable price. C3 matches the original Lamborghini 2x2, 3K twill carbon weave perfectly for a uniquely Lamborghini appearance. We have combined matte and gloss finish on the plenum cover to make your Urus truly stand out.  The C3 carbon fiber engine bay is the perfect upgrade to show off the Urus's one-of-a-kind engine. FEATURES: Autoclaved pre-preg dry carbon fiber with 2x2, 3K Twill Weave matched to Lamborghini OEM carbon fiber Clear-coated with automotive urethane, hand polished to a mirror finish OEM-perfect fit Installs easily without any modifications Digitally 3D laser scanned for guaranteed fitment Autoclave formed in billet aluminum molds at more than 100 psi and 2000 F Experience the Difference of C3 Carbon Products Competition Carbon Components (C3 Carbon) has been steadily gaining in popularity amongst today’s high-performance driving enthusiasts due to several key factors that help C3 Carbon stand out in a market full of sub-par aftermarket offerings. Each C3 Carbon product is manufactured to provide perfect fit and extreme strength while reducing weight, maximizing quality and ensuring years of exceptional finish. We provide all of this for significantly less money than OEM parts. Every product we make uses pre-impregnated dry carbon formed in a CNC-machined billet aluminum mold which is manufactured by laser-scanning the OEM component(s) so you know you’ll have a perfect fit, every time. Dry carbon is stronger and lighter than wet carbon, often weighing 1/3 of our competitors’ products. Our manufacturing methods also produce a smoother surface on each part for more dimensional accuracy; shaving edges, widening mounting holes and flexing pieces to make them fit are a thing of the past. C3 Carbon also applies an automotive urethane clear-coat which is U/V cured for durability and guarantees C3 Carbon parts won't yellow over time. Many of our competitors use wet carbon (which is heavier), and some use fiberglass with a carbon overlay (much heavier, as the carbon fiber has epoxy literally painted onto it). These materials and manufacturing methods produce a poor finish due to air contamination, and because the epoxy isn’t applied uniformly throughout the weave. These products are also much weaker than C3 Carbon products. Finally, most competitors use a fiberglass mold, which is far less expensive but cannot maintain the strict tolerances we demand of our own products. In the end, the fit and finish simply cannot stand up to C3 Carbon products.

AP Racing by Essex 2-piece "S" Vane J Hook Front Brake Rotors (Front 408 x 34mm)- Porsche 992 Turbo Iron Rotors Fit The Following Cars (w/ OEM Iron Rotors) Porsche 992 Turbo OEM Iron (Front) Sold/priced per pair. AP Racing 2-piece S Vane Competition J Hook front disc pair for GT4RS with iron or PCCB discs. Massive increase in airflow, cooling capacity, and durability vs. OEM discs or even conventional curved vane discs 408mm x 34mm (16.06" x 1.34") , 84 Sinusoidal "wave" vanes, D62 radial depth Designed for: club racing, time trial, autocross, HPDE Works with OEM calipers, no modifications required Ultralight, fully floating, anodized billet aluminum hat with float control/anti-rattle clips We are introducing a new internal vane technology in our front 2-piece discs for the GT4RS. It is called the Sinusoidal Vane, which AP sometimes refers to internally as the 'Wave' Vane for obvious reasons as you’ll see below. This tech is something that has helped AP Racing brake systems win championships in international GT racing, as well as multiple NASCAR Cup championships here in North America. As one of the most desirable track weapons on the planet, we wanted the GT4RS to be the first production car application for this technology in North America. Just as AP Racing's Radi-CAL calipers set a new benchmark for caliper stability, cooling, and durability, the Sinusoidal Vanes have done the same for iron racing discs. The concept for this disc design originated in NASCAR Cup. Up until the debut of the Next Gen car (for which AP/Essex are supplying the spec brake package), we were cramming our brake systems inside tiny 15” wheels. Trying to squeeze adequate brake thermal mass into a wheel that small is incredibly challenging, particularly when you have a 1,000 HP and 3,000 pounds mashing on them every few seconds from 200 mph…for hours on end! In a wheel that small, there isn’t anywhere for the heat to go, and the durability of every component is crucial. We were constantly looking for ways to provide the Cup teams with increased durability, stability, and cooling, and that’s what led AP to this technology. Benefits of the Wave Vane disc technology vs. traditional curved vanes: Increased thermal stability- Wild temperature swings are what causes discs to crack. When you stand on the brakes for an approaching corner, your disc temperatures skyrocket and the iron expands. As you travel down the subsequent straight, the discs are blasted with cooling air. The longer the straight and the higher the speed, the greater the temperature drop, and the further the iron contracts. This expansion and contraction cycle places a huge amount of stress on the iron and is what causes them to eventually crack. That’s why tracks with relatively slow corners at the end of high-speed straights, followed by another long straight, decimate brake discs (think Watkins Glen or Road America). In an ideal world, once you brought your discs up to race temps, you would keep them at a constant temperature for the entire session. The Sinusoidal Vane brings the discs closer to that goal by decreasing the difference between the maximum and minimum disc temperature by as much as 35%. That means a less dramatic temperature swing and greater crack resistance and durability. Reduced maximum disc temperatures by 10%+: Not only are temperature swings less intense with the Wave Vane, the maximum temperatures reached are substantially lower. For example, in one NASCAR test the Wave Vane discs showed a peak temp of 1328F and a minimum temp of 1085F (delta of 243F), while the traditional curved vanes maxed out at 1490F and a min of 1121F (delta of 369F). Not only was the difference between min and max more subdued, the max temperature reached by the Wave Vane disc was 162F lower! Increased cooling surface area- Each of the internal Wave Vanes has a larger cooling surface area vs. a traditional curved vane. Greater support for the disc face- A disc’s internal vane structure provides the support lattice behind the disc face. Having many internal vanes impacts airspeed and heat transfer through the disc, reduces air recirculation between vanes, and reduces deflection at the disc face. In practical terms, a disc with a high number of vanes is more thermally stable, maintains more even contact with the brake pads (which reduces uneven pad deposits/judder), and is less prone to distortion. In summary, the Wave Vane design provides even greater support for the disc face than AP’s standard curved vane designs. Reduced weight- The Wave Vane design provides a slight unsprung weight reduction vs. a similar disc with curved internal vanes.

Visually inspect your discs.  They should be a blue/grey color (instead of shiny silver), and have an even layer of pad material across and around the entire rotor face. If the AP Racing rotors don’t have a layer of pad material on them, perform another series of stops in the manner outlined above.
