2022-2026+ Audi RS3 / S3 (8Y) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2022-2026+ Audi RS3 / S3 (8Y) Carbon Ceramic Brake Kit — OEM-Size Replacement
The 8Y RS3 and S3 use different OEM brake packages, so this StopFlex replacement kit is built around the exact factory rotor sizes on the order: RS3 375 mm iron or 380 mm carbon-ceramic front with 310 mm rear, and S3 340 mm front with 310 mm rear. Carbon-ceramic rotors reduce unsprung mass and brake dust versus iron while adding heat stability for repeated hard stops on a compact AWD chassis that loads the front axle heavily. The kit includes matched carbon-ceramic rotors, pads, hats, and floating hardware so the replacement stays tied to the factory caliper and parking-brake architecture for the selected trim.
- RS3 8Y fitment is limited to the listed OEM-size front package: 375 mm iron replacement or 380 mm factory carbon-ceramic replacement, both paired with 310 mm rear rotors.
- S3 8Y fitment is limited to the 340 mm front and 310 mm rear OEM-size brake package; this is not a big-brake conversion or an RS3 caliper swap.
- Floating hats and hardware are included to manage radial heat growth in the carbon-ceramic disc while retaining the selected 8Y RS3/S3 rotor diameter and offset.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Audi RS3 / S3 (8Y) |
| Model years | 2022-2026+ |
| Front rotor reference | RS3: 375mm, 380mm (CCB); S3: 340mm |
| Rear rotor reference | RS3: 310mm; S3: 310mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 19" (for the 375 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 375 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 2022-2026+ Audi RS3 or S3 8Y?
No. Compatibility is limited to the exact trim and rotor-size combinations listed on this page: RS3 with 375 mm or 380 mm front rotors and 310 mm rear rotors, or S3 with 340 mm front rotors and 310 mm rear rotors. Confirm your current rotor diameter before ordering.
Does the kit keep the factory electronic parking brake and Auto Hold?
Yes, this OEM-size replacement approach retains the 8Y rear brake layout, including the electronic parking brake function, when ordered for the correct RS3 or S3 310 mm rear setup.
Why replace the factory iron brakes with carbon-ceramic on an 8Y RS3 or S3?
Carbon-ceramic rotors reduce rotating and unsprung mass, produce much less visible wheel dust than iron, and maintain friction stability at higher brake temperatures. That matters on the RS3 and S3 because repeated high-speed stops concentrate heat in the front brake package.
What should I verify before ordering?
Verify model year, trim, current front rotor diameter, rear rotor diameter, wheel clearance, and whether the car has the RS3 380 mm carbon-ceramic package or the smaller iron package. If the car has aftermarket calipers or non-OEM rotor sizing, this OEM replacement page is not the correct fitment.
Need Fitment Confirmation?
Send the exact vehicle details, current rotor sizes, and caliper type before ordering.
