Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2005-2011 Audi RS6 (C6). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2005-2011 | Akebono OEM Audi RS 6-Piston (9N) Caliper / 400mm | TTSPORT EP4 4-Piston Forged Caliper integrated with EPB / 380mm | 20" |
Fitment here is bespoke: brackets, hat offsets, and caliper mounting are engineered for your exact model and trim rather than copied across the platform. Two trims with the same chassis code can still differ in knuckles, hub geometry, and wheel ET clearance — which is why we confirm your trim first, then build the matched system of calipers, pads, rotor hats, floating hardware, and lines for it. Modified knuckles, uprights, or non-factory suspension points require review before ordering.
The 400 mm rotor sets the minimum wheel size at 20" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |
|---|---|
| 15" | 260 mm – 285 mm |
| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |

Why Carbon Ceramic — and Why StopFlex
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Winter & Cold-Weather Braking
A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose Street Spec.
Caliper Overview
Front Caliper
The front caliper is the Akebono OEM Audi RS 6-Piston (9N) unit, the same design Audi fits to its RS-line factory ceramic setups. Six pistons give even pad loading across a 400mm disc, so pedal pressure stays consistent from cold city stops through repeated high-speed braking.
Rear Caliper
The rear is the TTSPORT EP4 4-Piston Forged Caliper, a two-piece forged-aluminum body with four 28mm hydraulic service pistons plus a dedicated 27mm EPB actuator piston, so your factory electronic parking brake keeps working while the rear axle gains real thermal capacity. It carries two-piece heat-insulated pistons with dust boots, roughly 30.4 cm² of total piston area, weighs about 4.50 kg per caliper without pads, and pairs with a 380mm rear rotor.
Choose Your Rotor: Street, Track-Day, or Motorsport

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.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat still soaks 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.

FAQ
Will this kit clear my wheels on the RS6 C6?
The front rotor is 400mm, so you need at least 20-inch wheels, and spoke shape matters as much as diameter. Send us your exact wheel model and offset during fitment confirmation and we'll check spoke clearance against the Akebono 9N caliper before we build anything.
How does this brake in cold winter weather?
A cold, untuned carbon-ceramic disc bites less than cold iron on the very first stops. That's physics, not a fault. We tune both the pad compound and the disc's ceramic coating for cold starts, so on the RS6 winter cold-car feel now lands very close to summer feel. Still leave a little extra following distance on the first stops of a freezing morning.
Is this a universal C6 platform kit or built for my specific car?
It's bespoke per trim. The RS6 C6 uses different front knuckles and hub geometry than the standard A6/S6 in the same chassis family, so we cut brackets, set rotor-hat offsets, and match caliper mounting to your confirmed RS6 build. We do not sell a platform-wide bolt-on and assume it fits.
Will my factory parking brake still work?
Yes. The RS6 C6 uses a factory electronic parking brake, and the TTSPORT EP4 rear caliper includes a dedicated EPB actuator piston. You keep the OE electronic parking-brake function while adding rear-axle thermal capacity on a 380mm rotor.
