AP Racing J Hook 350x28mm Replacement Rear Brake Rotor Rings This kit is two replacement rotor discs and new installation hardware only. Center hats are not included. Replacement rotor rings for AP Racing 13.01.20014. Fits The Following Cars (w/ OEM iron rotors): Porsche 992 911 S/4S/GTS Porsche 991 911 S/4S/GTS Sold/priced per pair of rotor rings (including hardware). 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 Discs 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.

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 Discs 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.

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.
