2012-2018 Audi RS6 / S6 (C7) Carbon Ceramic Brake Kit — OEM-Size Replacement
The C7 RS6/S6 is a heavy 4.0T quattro sedan/Avant platform, so repeated high-speed stops can expose heat fade, pad transfer, rotor checking, and heavy iron-rotor dust. This StopFlex OEM-size carbon-ceramic replacement kit is built around the listed factory brake packages: RS6 390 mm or 420 mm carbon-ceramic front rotors with 356 mm rears, and S6 400 mm fronts with 356 mm rears. The carbon-ceramic rotors, pads, hats, and floating hardware are specified to reduce rotating mass and brake dust while keeping the original caliper architecture and factory-style fitment.
- C7 RS6 applications must be matched to the existing 390 mm or 420 mm front rotor package; those two front brake systems are not interchangeable by visual trim name alone.
- C7 S6 fitment on this page is for the OEM 400 mm front and 356 mm rear rotor setup, not smaller A6/A7 brakes or aftermarket big-brake conversions.
- The kit includes carbon-ceramic rotors, matching pads, hats, and floating hardware so the friction pair and rotor mounting system are replaced together, not mixed with worn iron-brake components.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Audi RS6 / S6 (C7) |
| Model years | 2012-2018 |
| Front rotor reference | RS6: 390mm, 420mm (CCB); S6: 400mm |
| Rear rotor reference | RS6: 356mm; S6: 356mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 20" (for the 390 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 390 mm rotor, so the minimum wheel size is 20". Wheels under 20" 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 2012-2018 Audi RS6 or S6 C7?
No. Compatibility is limited to the exact C7 RS6 and C7 S6 trim and rotor sizes listed on this page. Confirm your front rotor diameter before ordering: RS6 390 mm or 420 mm carbon-ceramic, and S6 400 mm. Rear fitment listed here is 356 mm.
Will the electronic parking brake and Auto Hold still work?
Yes, when ordered for the correct 356 mm rear setup, the kit is designed as an OEM-size rotor replacement and retains the factory rear caliper and electronic parking brake system. It does not convert the rear brake to a separate motorsport handbrake or delete EPB hardware.
Why replace the factory iron brakes with carbon-ceramic on a C7 S6?
The S6’s 400 mm front iron rotors carry significant rotating mass and produce visible dust on open-wheel setups. Carbon-ceramic replacement rotors reduce unsprung and rotating weight, run cleaner, and are more stable under repeated heat cycles than conventional iron discs when paired with the supplied pads.
What should I confirm before placing the order?
Confirm model, year, front rotor diameter, rear rotor diameter, caliper type, wheel size and barrel clearance, and whether the car currently has iron or OEM carbon-ceramic brakes. A VIN, rotor measurement, and photos of the front and rear calipers help prevent ordering a 390 mm, 400 mm, or 420 mm package for the wrong brake setup.
Need Fitment Confirmation?
Send the exact vehicle details, current rotor sizes, and caliper type before ordering.
