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 J Hook Brake Rotors – The Gold Standard in Track Day & Racing Performance
Engineered for professional motorsport, HPDE, and dedicated track day use, AP Racing’s J Hook Brake Rotors deliver uncompromising performance, thermal stability, and consistent braking power. These two-piece, floating rotors are built to handle the extreme demands of road racing, with design features derived from over 50 years of elite competition—including Formula 1, NASCAR, and IMSA.
Unlike conventional one-piece rotors, AP Racing’s two-piece floating design features a billet aluminum hat mated to a cast iron disc via precision-engineered bobbins. This setup allows for controlled radial expansion under high heat, minimizing distortion and coning. The result? More even pad wear, a firmer pedal feel, and longer component life, even during extended lapping sessions or endurance racing. Floating hardware includes anti-knockback spring clips that reduce piston retraction while eliminating common NVH issues like rattling.
Why Choose AP Racing J Hook Rotors? 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.

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.

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.

AP Racing J Hook Brake Rotors – The Gold Standard in Track Day & Racing Performance
Engineered for professional motorsport, HPDE, and dedicated track day use, AP Racing’s J Hook Brake Rotors deliver uncompromising performance, thermal stability, and consistent braking power. These two-piece, floating rotors are built to handle the extreme demands of road racing, with design features derived from over 50 years of elite competition—including Formula 1, NASCAR, and IMSA.
Unlike conventional one-piece rotors, AP Racing’s two-piece floating design features a billet aluminum hat mated to a cast iron disc via precision-engineered bobbins. This setup allows for controlled radial expansion under high heat, minimizing distortion and coning. The result? More even pad wear, a firmer pedal feel, and longer component life, even during extended lapping sessions or endurance racing. Floating hardware includes anti-knockback spring clips that reduce piston retraction while eliminating common NVH issues like rattling.
Why Choose AP Racing J Hook Rotors? 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.

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.

The Strongest Roll Bar Available For The Gen 5 Camaro
The CMS Performance Gen 5 Camaro Roll Bar is the strongest, safest, and most beautifully constructed roll bar on the market. In designing the Camaro roll bar, safety, strength, and structural integrity were our primary goals. Fully TIG welded from Docol R8 Advanced High-Strength Steel allows us to design a roll bar that is stronger and lighter! Our innovative design maximizes the room for the factory Recaro seats, meaning taller drivers can send their seat all the way back and still maintain a comfortable recline.
Precision CNC machined solid steel interlocking roll bar clamps on the kicker mounting plates help make installation a snap. Free custom powder-coating gives you a premium, finished look without breaking the budget. Add the optional custom-cut Rear Seat Delete Kit and you've got a fully trimmed-out roll bar installation that performs as great as it looks. Our Camaro roll bar forms the perfect foundation for taking your safety up a huge notch.
Roll Bar Safety and Strength Are The Priority
Safety is the main reason to install a roll bar in the first place. As racers ourselves, we sweat the details. That's why we use 1.75" x .095" Docol R8. Docol is 15% stronger than 4130 CrMo, and much less brittle. Docol R8 also dissipates impact energy more effectively. It's the same tubing used in full-competition road racing roll cages because, first and foremost, it's a roll bar not a trim piece.
Our beefy main hoop straddles the rear seat cross member, a much stronger location than the rear footwell, eliminating the need for underbody backing plates. Taking a cue from NHRA cage design, the diagonal supports feature a concave design to allow full front-seat travel while distributing roll-over energy between the main hoop and kickers. The harness cross-bar is precisely located to put your shoulder straps at both the proper angle (0° to -20°) and distance to the driver. Finally our rear kickers bolt to a reinforced corner of the rear seat floor, again requiring no backing plates beneath the floor pan.
Objects in Your Rear View Mirror Are Clearly Visible
A clear rear view is an important component of safety both on and off the race track. Our use of stronger materials and innovative design lets us keep your rear view unobstructed by additional bracing. This also helps weight down. Every detail of the CMS Gen 5 Camaro roll bar is engineered with safety as our primary goal.
American-Made Roll Bar For An American Icon
Click Here for Installation Instructions
Okay, another reason we install roll bars is that they look cool. We're gear heads, we get that. Each CMS Performance Gen 5 Camaro roll bar is handcrafted right here in America by master fabricators for a perfect fit, beautifully 360o TIG welded for high strength, and fully powder-coated in our facility for a brilliant, durable finish. There's no extra charge for custom colors. CMS operates a complete powder-coating facility to offer you color-matched Camaro factory colors1, giving your Camaro a personalized look that will last.
None of your interior trim panels need to be eliminated or cut. Your rear seat back can be re-installed, or you can opt for our custom Shrader rear seat delete, the perfect place to put a track bag, helmet and HANS, driver cooling system, etc. (you can hide stuff under there, too). If you ever want to put your car back to stock, it will go back together as though the roll bar was never there.
Complete, detailed instructions make installation pretty simple (figure about two hours if you're reasonably handy), and all Grade 8 hardware needed is shipped with your CMS Performance roll bar. Add Racing Harnesses and a Head-And-Neck Restraint and and you're ready to hit the track safe and secure.

Litespeed GT7 Forged Magnesium Wheel
from $2,125.00
Litespeed Racing GT7 Forged Magnesium Wheel
Light, Stiff, and Strong: Pick All Three
The Litespeed Racing GT7 Forged Magnesium wheel is their stiffest wheel design, and also one of Litespeed's lightest wheels. Road course and autocross racing require a very stiff, strong wheel. Wheel flex can hurt lap times just as much as added weight can. Countless hours of FEA computer simulations where devoted to fine tuning every aspect of the Litespeed GT7’s geometry, with a focus on high strength and stiffness. This FEA design also resulted in the Litespeed GT7 featuring deep spokes with side pocketing for weight reduction.
Litespeed Racing wheels are competition-proven on tracks across the world, from road courses to autocross to quarter-mile and half-mile top speed races.
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!

Forgeline GS1 Wheels (5 Lug)
Contact a wheel specialist today at 844-438-7244 to discuss the details of your custom Forgeline wheel build. We can guide you through sizing, offsets, finishes, and other details to make sure your Forgelines are perfectly suited to your needs!
If you want to use the same wheel that has carried many top-level professional road racing teams to victory, but prefer a slightly less aggressive posture that is perhaps a bit more friendly for your street-driven sports car, then the GS1 is made for you!
Based on our extremely successful GS1R wheels (which was originally designed for professional racing teams competing in the IMSA Continental Tire SportsCar Challenge Grand Sport (GS) class), the Forgeline GS1 combines the latest in advanced wheel technology, including one piece forged monoblock construction, motorsport engineered design, and I-beamed spokes. And just like the GS1R, the GS1 is engineered to withstand the rigors of top-level endurance racing with a 2100 lb street tire load rating and exceptional deflection stiffness.
Though made from the same forgings and similar design as our race-winning GS1R (including the distinctive smooth chamfered outer edge), the GS1 forgoes the GS1R’s aggressive open-lug center area for a more traditional (perhaps “gentlemanly”) center design that accommodates our standard press-in aluminum center cap.
The GS1 is machined from a single forging of 6061-T6 aluminum. It is currently available in 17, 18, 19, 20, 21, and 22-inch diameters with a range of widths and offsets. And just like any Forgeline wheel, the GS1 is available with fully customizable finish options.
