2003-2013 Audi A3 / S3 / RS3 (8P) CCB Big Brake Kit — Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup
The Audi 8P owner shopping this kit is usually solving heat saturation, rotor vibration, brake dust, and front-axle weight from an iron big-brake setup used hard on street or track. StopFlex pairs 380 mm carbon-ceramic rotors with the Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper up front and a 380 mm TTSPORT EP4 rear package, giving the 8P chassis more thermal capacity with lower rotating mass and cleaner open-wheel appearance. Because A3, S3, and RS3 8P trims can differ in knuckles, hub position, and wheel offset, the brackets and rotor hats are engineered for the confirmed car rather than assumed from the shared chassis code.
- 380 mm front and rear carbon-ceramic rotors require 19 inch or larger wheels on the Audi 8P; spoke clearance must still be checked with the selected wheel design.
- Front braking is built around the Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper, not a generic 4-piston conversion.
- A3, S3, and RS3 8P fitment is validated per trim because RS/performance uprights, hub geometry, and wheel ET clearance may not match standard A3 hardware.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 380 mm front 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.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses the Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper, giving the 380 mm rotor a large, rigid multi-piston clamp pattern for more even pad loading and a firmer pedal under repeated high-speed stops. Its credibility comes from being an OEM-derived Audi RS Akebono caliper rather than an anonymous aftermarket casting, so the upgrade uses proven production performance-brake architecture. StopFlex matches the caliper mount, rotor hat offset, and line package to the exact A3, S3, or RS3 8P trim being built.
Rear Caliper (Balance)
The rear axle uses the TTSPORT EP4 4-Piston Caliper with EPB on a 380 mm carbon-ceramic rotor to add rear thermal capacity and help keep the car settled under trail braking and repeated deceleration. The EP4 architecture uses four hydraulic service pistons plus a dedicated EPB actuator piston, but the factory Audi 8P parking-brake system must be confirmed because the chassis was originally cable-handbrake based.
Front & rear, engineered together: This kit is engineered as a front-and-rear system so front piston area, rear service-piston support, rotor diameter, pad compound, and brake-line routing are specified together rather than pairing a large front brake with an under-capacity rear axle. The TTSPORT EP4 rear caliper preserves an EPB-capable rear architecture while the Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper supplies the main front-axle braking load, allowing StopFlex to set the hardware around the specific 8P trim and wheel package.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

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.
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 380 mm kit fit my exact Audi A3, S3, or RS3 8P?
Fitment is built around your confirmed trim, drivetrain, hub/knuckle package, and wheel data. StopFlex does not treat every 8P as the same car; brackets, rotor-hat offsets, caliper mounting, and line routing are matched to the exact A3, S3, or RS3 specification before the kit is made.
What wheel size do I need for the 380 mm rotors?
The 380 mm front and rear rotors require 19 inch or larger wheels. Diameter clearance is only the first check; spoke shape, barrel profile, wheel offset, and any spacer plan must be verified against the Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper and TTSPORT EP4 rear caliper.
Will the electronic parking brake still work on my 8P?
The 2003-2013 Audi 8P chassis did not leave the factory with an EPB; it uses a manual cable handbrake. The rear caliper in this kit is EPB-capable, so StopFlex must confirm the parking-brake strategy for your specific build before order approval.
Why choose carbon-ceramic rotors instead of another iron big-brake kit?
Carbon-ceramic rotors reduce rotating and unsprung mass compared with iron rotors of similar size, produce less visible brake dust, and tolerate repeated heat cycles without the same thermal load on the rotor face. On an 8P used for fast road or track work, the 380 mm rotor size adds heat capacity while the lower rotor mass helps steering response and suspension control.
