2020-2026+ Toyota GR Supra / Supra (A90/A91) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2020-2026+ Toyota GR Supra / Supra (A90/A91) Carbon Ceramic Brake Kit — OEM-Size Replacement
The A90/A91 GR Supra 3.0 is hard on its 348mm front and 345mm rear iron rotors when repeated high-speed stops put heat into a relatively compact 19-inch-wheel brake package. This StopFlex OEM-size carbon-ceramic replacement kit keeps the factory rotor diameters, caliper locations, rear parking-brake function, and wheel fitment envelope while adding carbon-ceramic heat stability, lower brake dust, and reduced rotating mass. It is for Supra/GR Supra applications that match the listed 348mm front and 345mm rear rotor setup only.
- Designed around the GR Supra 3.0/A90/A91 348mm front rotor reference and 345mm rear rotor reference, not the smaller 2.0 brake package.
- OEM-size carbon-ceramic rotors work with the factory fixed front caliper layout and rear EPB-equipped brake architecture when the vehicle matches the listed rotor sizes.
- Kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware for owners replacing heat-checked, warped, or dust-heavy factory iron rotors without changing caliper brackets.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Toyota GR Supra / Supra (A90/A91) |
| Model years | 2020-2026+ |
| Front rotor reference | GR Supra (3.0): 348mm |
| Rear rotor reference | GR Supra/Supra: 345mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 18" (for the 348 mm rotor) |
For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
This setup uses a 348 mm rotor, so the minimum wheel size is 18". Wheels under 18" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

FAQ
Will this fit every 2020-2026+ Supra?
No. This page is limited to A90/A91 Toyota GR Supra/Supra applications that use the listed 348mm front and 345mm rear rotor sizes. Confirm your trim, rotor diameter, and caliper package before ordering; smaller 2.0 brake setups are not covered by this kit.
Will my factory electronic parking brake and auto-hold still work?
Yes, when the car matches the 345mm rear application listed for this page, the rear rotor and hat package is built to retain the factory rear parking-brake architecture. The kit does not require deleting the EPB system.
Why switch from the OEM iron rotors on a GR Supra 3.0?
The 3.0 Supra can overheat iron rotors during repeated track braking, especially with sticky tires and short cooldown laps. Carbon-ceramic rotors maintain friction stability at higher temperatures, cut visible brake dust on the open factory wheels, and reduce rotating mass at all four corners.
What should I verify before placing the order?
Verify A90/A91 chassis, model year, trim, front rotor size of 348mm, rear rotor size of 345mm, and wheel clearance if you run aftermarket wheels. Factory 19-inch GR Supra 3.0 wheels are the intended fitment envelope, but aftermarket barrel and spoke shapes must be checked.
Need Fitment Confirmation?
Send the exact vehicle details, current rotor sizes, and caliper type before ordering.
