2019-2026+ Audi RS6 / S6 (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 RS6 / S6 (C8) Carbon Ceramic Brake Kit — OEM-Size Replacement
The C8 RS6 and S6 are heavy, high-output Audi sedans/wagons that load their front brakes hard, especially during repeated highway-speed stops, mountain driving, or track sessions. This StopFlex OEM-replacement kit keeps the factory brake architecture and matches the listed rotor packages: RS6 420mm or 440mm front with 370mm rear, and S6 400mm front with 350mm rear. Carbon-ceramic rings reduce heat-related fade, brake dust, and rotating unsprung mass while retaining the correct hats, pads, and floating hardware for the specified C8 fitment.
- Built only for C8 RS6 / S6 applications using the listed OEM-size rotor packages: RS6 420mm or 440mm front with 370mm rear, and S6 400mm front with 350mm rear.
- Carbon-ceramic replacement targets the C8 owner replacing worn iron rotors, reducing wheel dust on open Audi wheels, or avoiding dealer-level cost when OEM CCB rotors are cracked or at wear limit.
- Includes carbon-ceramic rotors, matched pads, vehicle-specific hats, and floating hardware so the rotor assembly interfaces with the factory caliper and hub layout for the selected trim and rotor size.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Audi RS6 / S6 (C8) |
| Model years | 2019-2026+ |
| Front rotor reference | RS6: 420mm, 440mm (CCB); S6: 400mm |
| Rear rotor reference | RS6: 370mm; S6: 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 fit every 2019-2026+ Audi RS6 or S6 C8?
No. Fitment is limited to the exact C8 RS6 and S6 trims and rotor sizes listed on this page. Confirm whether your car uses RS6 420mm or 440mm front rotors with 370mm rear rotors, or S6 400mm front rotors with 350mm rear rotors before ordering.
Does this kit keep the factory electronic parking brake and Auto Hold?
Yes, when ordered for the correct rear rotor package, the kit replaces the rotor assembly and pads while retaining the factory rear caliper and parking-brake system. EPB service mode and any required post-service procedures should be handled with Audi-compatible diagnostic equipment.
Why switch a C8 RS6 or S6 from iron rotors to carbon ceramic?
Carbon ceramic reduces brake dust, lowers rotating unsprung mass, and holds friction stability better under repeated heat cycles than iron. On the C8 RS6 / S6, those gains matter because the car combines high curb weight, high speed, and large front rotor packages.
What should I verify before placing the order?
Verify model, year, trim, front and rear rotor diameter, current brake option, caliper type, and wheel clearance. The 420mm and 440mm RS6 front packages need the correct factory brake hardware and enough inner wheel-barrel clearance.
Need Fitment Confirmation?
Send the exact vehicle details, current rotor sizes, and caliper type before ordering.
