2019-2026+ Audi RS7 / S7 (C8) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2019-2026+ Audi RS7 / S7 (C8) Carbon Ceramic Brake Kit — OEM-Size Replacement
The C8 Audi RS7 and S7 put heavy thermal load into large OEM brakes, so owners usually shop carbon ceramic when iron rotors are dusting, juddering after heat cycles, or when factory CCB discs need replacement at dealer-level cost. This StopFlex OEM-size kit matches the listed C8 brake packages: RS7 420 mm or 440 mm front with 370 mm rear, and S7 400 mm front with 350 mm rear. Carbon-ceramic rotors reduce rotating unsprung mass, handle repeated high-speed stops with more stable friction, and keep the factory-style rotor diameter, hat offset, pads, and floating hardware layout for fitment confidence.
- RS7 fitments are limited to the listed C8 rotor packages: 420 mm front or 440 mm carbon-ceramic front, paired with 370 mm rear rotors.
- S7 fitment is limited to the C8 400 mm front and 350 mm rear rotor package, not smaller A7 brake packages or RS7-only 370 mm rear setups.
- The kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware, so the friction ring and mounting system are supplied as a matched OEM-size replacement package.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Audi RS7 / S7 (C8) |
| Model years | 2019-2026+ |
| Front rotor reference | RS7: 420mm, 440mm (CCB); S7: 400mm |
| Rear rotor reference | RS7: 370mm; S7: 350mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 21" (for the 420 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 420 mm rotor, so the minimum wheel size is 21". Wheels under 21" 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 kit fit every 2019-2026+ Audi RS7 or S7 C8?
No. Compatibility is limited to the exact trim and rotor sizes on this page: RS7 with 420 mm or 440 mm front rotors and 370 mm rear rotors, or S7 with 400 mm front and 350 mm rear rotors. Confirm your current rotor diameter, brake code, and wheel clearance before ordering.
Does the rear electronic parking brake and auto-hold function stay in place?
Yes, this is an OEM-size replacement package that retains the vehicle’s rear brake architecture rather than converting to a universal motorsport caliper. The C8 rear EPB and auto-hold system should remain functional when installed with the correct RS7 370 mm rear or S7 350 mm rear fitment.
Why replace the factory iron brakes with carbon ceramic on a C8 RS7 or S7?
Carbon ceramic reduces brake dust on open Audi wheels, cuts rotating unsprung mass compared with iron, and resists heat-related fade during repeated high-speed stops. It is most useful for C8 RS7 and S7 owners who drive hard enough to overheat iron rotors or who want cleaner wheels and sharper response without changing rotor size.
What should I verify before ordering this OEM replacement kit?
Measure the front and rear rotor diameters, confirm whether the RS7 has 420 mm iron or 440 mm CCB front brakes, verify the S7 uses the 400 mm front and 350 mm rear setup, and check wheel barrel clearance. The kit is not a generic C8 A7/S7/RS7 brake conversion.
