2007-2013 Audi RS3 / S3 (8P) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2007-2013 Audi RS3 / S3 (8P) Carbon Ceramic Brake Kit — OEM-Size Replacement
The 8P RS3 and S3 put real heat into a compact MQB-predecessor chassis brake package, especially on tuned cars, fast road use, and repeated track braking. This StopFlex OEM-replacement kit keeps the factory rotor diameters for the listed trims: RS3 370mm front and 310mm rear, S3 345mm front and 310mm rear, with carbon-ceramic rotors, matched pads, hats, and floating hardware. The payoff is lower rotating mass, reduced brake dust, and more stable friction at temperature without changing the car to an oversized big-brake conversion.
- Built only for 8P RS3 applications with 370mm front / 310mm rear rotors and 8P S3 applications with 345mm front / 310mm rear rotors.
- OEM-size carbon-ceramic replacement keeps the factory caliper location and rotor envelope instead of forcing an upsized front brake conversion.
- Floating hats and hardware are included so the carbon-ceramic rings can expand under repeated heat cycles on track or mountain-road use.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Audi RS3 / S3 (8P) |
| Model years | 2007-2013 |
| Front rotor reference | RS3: 370mm; S3: 345mm |
| Rear rotor reference | RS3: 310mm; S3: 310mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 19" (for the 370 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 370 mm rotor, so the minimum wheel size is 19". Wheels under 19" 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 2007-2013 Audi A3, S3, or RS3 8P?
No. This page is limited to the exact 8P RS3 and 8P S3 brake sizes listed here: RS3 370mm front / 310mm rear and S3 345mm front / 310mm rear. Standard A3, TDI, 2.0T, and other rotor-size variants are not covered by this fitment.
Do I need different wheels or calipers?
The kit is designed around the OEM rotor diameters for the matching trim, so it is not an oversized brake conversion. Wheel clearance should match the factory RS3 370mm or S3 345mm front brake envelope, but StopFlex should verify your wheel, spacer, and caliper clearance before shipment.
Will the parking brake still work?
Yes, the rear package is built around the listed 310mm rear rotor setup and does not require deleting the rear parking-brake function. Confirm the car has the correct 8P RS3/S3 rear caliper and 310mm rotor configuration before ordering.
Why switch from iron rotors to carbon-ceramic on an 8P RS3 or S3?
Carbon-ceramic rotors reduce rotating and unsprung mass, create far less visible dust on open wheels, and tolerate repeated high-temperature stops better than comparable iron discs. The benefit is most noticeable on tuned 8P cars, track days, and drivers who are replacing iron rotors frequently.
