2012-2017 Audi S8 (D4) Carbon Ceramic Brake Kit — OEM-Size Replacement
The D4 Audi S8 puts a 4.0T, quattro drivetrain, and long-wheelbase sedan mass behind a large factory brake package, so owners shop carbon ceramic when 400mm iron fronts create dust, heat soak, or repeated-service cost. This StopFlex OEM-size replacement kit is built around the S8 rotor references on this page: 400mm front iron fitment, 380mm front CCB fitment, and 356mm rear. The kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware so the decision comes down to confirming your exact factory rotor size and caliper package before ordering.
- Built for 2012-2017 Audi S8 D4 applications using the listed OEM-size references: 400mm front, 380mm front CCB, and 356mm rear.
- The 400mm S8 front setup uses a large fixed front caliper; StopFlex pads are matched to the OEM pad shape for the compatible caliper and rotor combination.
- Carbon-ceramic rotors reduce brake dust and rotating mass compared with the S8 iron rotor package while adding high-temperature stability for repeated highway or track-session braking.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Audi S8 (D4) |
| Model years | 2012-2017 |
| Front rotor reference | S8: 400mm, 380mm (CCB) |
| Rear rotor reference | S8: 356mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 20" (for the 400 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 400 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 kit fit every 2012-2017 Audi S8 D4?
No. Compatibility is limited to the S8 D4 trims and rotor sizes listed on this page. Confirm whether your car has the 400mm front iron setup or the 380mm factory CCB front setup, and confirm the 356mm rear rotor before ordering.
Will my electronic parking brake and Auto Hold still work?
Yes, the rear package is designed around the OEM-size 356mm S8 rear brake configuration, so the factory rear caliper, electronic parking brake function, and Auto Hold logic are retained when the car matches the listed fitment.
Why replace the factory iron brakes with carbon ceramic on a D4 S8?
The D4 S8 is a heavy, high-power quattro sedan, and the 400mm iron front rotors carry significant rotating mass and generate visible dust. Carbon ceramic rotors cut dust, reduce unsprung and rotating weight, and hold friction more consistently under repeated high-speed stops.
What should I verify before placing the order?
Measure or decode the front rotor package, confirm the rear rotor is 356mm, check that your wheels clear the factory S8 calipers and rotor diameter, and send VIN or brake photos if the car has been converted from iron to CCB or modified.
Need Fitment Confirmation?
Send the exact vehicle details, current rotor sizes, and caliper type before ordering.
