2005-2011 Audi A6 / S6 / RS6 (C6) CCB Big Brake Kit — Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup
This 2005-2011 Audi A6 / S6 / RS6 C6 kit is for owners who have outgrown heavy iron rotors, brake dust, and heat fade on a large quattro chassis. The front axle uses a 420mm carbon-ceramic rotor with a Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper, while the rear uses a 380mm carbon-ceramic rotor with a TTSPORT EP4 4-Piston Caliper with EPB. StopFlex engineers the brackets, rotor-hat offsets, caliper mounting, lines, pads, and hardware to the confirmed A6, S6, or RS6 trim instead of assuming all C6 cars share the same brake geometry.
- 420mm front carbon-ceramic rotors require 21-inch or larger wheels; wheels under 21 inches will not clear this C6 package, and spoke clearance must still be checked.
- The kit pairs a Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper up front with a TTSPORT EP4 4-Piston Caliper with EPB and 380mm rear rotor for a full front/rear upgrade.
- A6, S6, and RS6 C6 variants can differ in knuckles, hub geometry, rotor offset, and wheel ET clearance, so StopFlex builds the hats and brackets to the confirmed trim, not just the chassis code.

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 420 mm front rotor, so the minimum wheel size is 21". Wheels under 21" 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 caliper is the Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper, giving the 420mm front rotor a large multi-piston pad load for stable clamping and consistent pedal response. Its credibility comes from being a genuine OEM-derived Audi RS/Akebono unit rather than a generic aftermarket casting. StopFlex matches the caliper position, bracket, hose, pad, and rotor-hat offset to the customer’s exact C6 configuration.
Rear Caliper (Balance)
The rear axle uses the TTSPORT EP4 4-Piston Caliper with EPB on a 380mm carbon-ceramic rotor to add rear thermal capacity without deleting the factory electronic parking brake. Its hydraulic service pistons support rear brake contribution and stability while the dedicated EPB actuator preserves parking-brake operation.
Front & rear, engineered together: This kit is engineered as a front/rear system so the 420mm 10-piston front package and 380mm EPB rear package are matched for rotor diameter, hat offset, caliper location, and line routing. A C6 buyer avoids the bias and heat-capacity mismatch that can result from adding a front-only big brake kit while leaving the rear axle thermally undersized.
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.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |

FAQ
Will this fit my exact Audi A6, S6, or RS6 C6?
Fitment is confirmed to your exact trim before production. StopFlex does not treat every C6 as the same car; brackets, rotor-hat offsets, caliper radial position, and brake-line routing are matched to the confirmed A6, S6, or RS6 configuration.
What wheel size is required for the 420mm front rotor?
The 420mm front rotor requires 21-inch or larger wheels. Wheels under 21 inches will not clear the package, and 21-inch wheels still need a spoke-clearance check against the Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper.
Will the electronic parking brake still work?
Yes. The rear package uses the TTSPORT EP4 4-Piston Caliper with EPB, which keeps a dedicated EPB actuator so the C6 retains factory parking-brake function while gaining a 380mm rear carbon-ceramic rotor.
Why move this C6 from iron brakes to carbon-ceramic?
Carbon-ceramic rotors reduce brake dust, cut rotating and unsprung mass compared with equivalent iron hardware, and tolerate repeated high-energy stops with less heat-related fade. On a heavy quattro A6/S6/RS6 C6, the payoff is cleaner wheels, sharper response, and more thermal margin.
