2015-2020 Audi RS3 / S3 (8V) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2015-2020 Audi RS3 / S3 (8V) Carbon Ceramic Brake Kit — OEM-Size Replacement
The 8V RS3 and S3 use different front brake packages, so this OEM-size StopFlex kit is built around the exact factory rotor diameter on the car: RS3 370mm iron, RS3 380mm carbon-ceramic, or S3 340mm front, with 310mm rear rotors. Carbon-ceramic rotors address the usual reasons these owners replace brakes: heat control under repeated hard stops, lower rotating unsprung mass, reduced brake dust on open Audi wheels, and a clean way to replace worn or cracked factory CCB discs without changing the vehicle’s basic brake layout. The kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware for the listed 8V RS3/S3 configurations only.
- Front rotor selection is trim-dependent: 8V RS3 uses 370mm iron or 380mm factory CCB sizing, while 8V S3 uses a 340mm front rotor; this page is not a one-size-fits-all 8V brake listing.
- The rear package is based on the 310mm 8V RS3/S3 rear rotor position and retains the factory-style electronic parking brake service procedure when installed with the correct rear configuration.
- Carbon-ceramic construction reduces brake dust and rotating mass versus factory iron discs, which is noticeable on S3/RS3 open-spoke wheels and during repeated high-speed braking on the MQB 8V chassis.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Audi RS3 / S3 (8V) |
| Model years | 2015-2020 |
| Front rotor reference | RS3: 370mm, 380mm (CCB); S3: 340mm |
| 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 kit fit every 2015-2020 Audi RS3 or S3 8V?
No. Compatibility is limited to the trims and rotor sizes listed on this page: RS3 370mm front, RS3 380mm carbon-ceramic front, S3 340mm front, and 310mm rear. Confirm your current rotor diameter before ordering.
Does the rear kit keep the electronic parking brake?
Yes, when matched to the correct 310mm rear configuration. The 8V rear caliper uses an electronic parking brake, so installation requires the normal Audi/VW EPB service-mode procedure for pad and rotor replacement.
Why replace the OEM iron brakes with carbon-ceramic on an 8V S3 or RS3?
The main reasons are lower brake dust, reduced rotating unsprung mass, and better temperature stability during repeated hard braking. RS3 owners often shop this kit after track heat or high replacement cost; S3 owners often want the same factory-size fit with less weight and dust.
What should I confirm before placing the order?
Confirm the model year, trim, front rotor diameter, rear rotor diameter, wheel clearance, and whether the car currently has iron or factory carbon-ceramic front brakes. The RS3 370mm, RS3 380mm CCB, and S3 340mm front setups are not interchangeable without selecting the correct kit.
