Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2019-2025 Audi RS7 (C8). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2019-2025 | Akebono OEM Audi S 6-Piston (8N) Caliper / 380mm | TTSPORT EP4 4-Piston Forged Caliper integrated with EPB / 380mm | 19" |
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 380 mm rotor sets the minimum wheel size at 19" — 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 |

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 S 6-Piston (8N) unit, the same monoblock design Audi fits to its S-line cars. Six pistons spread clamping evenly across the 380mm face, which keeps pedal feel firm and repeatable when you push a 600-plus horsepower RS7 hard.
Rear Caliper
The rear is the TTSPORT EP4 4-Piston Forged Caliper with an integrated EPB. Four 28mm hydraulic service pistons handle braking while a dedicated 27mm actuator piston preserves the C8's factory electronic parking brake, so you keep OE parking-brake function and gain real rear-axle thermal capacity on a two-piece forged-aluminum body of about 4.50 kg per caliper.
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
High rotor temperature tolerance does not mean heat management disappears. Under repeated hard braking, heat migrates into the pads, brake fluid, seals, calipers, and wheels even when the ceramic disc itself is comfortable. Plan brake cooling and high-temperature fluid for extended track sessions, long mountain descents, or sustained aggressive driving.
Get Your Fitment Confirmed
Before ordering, tell us the exact vehicle, current rotor sizes, and caliper type. Nothing goes to production until the build is confirmed against your VIN-level configuration.
FAQ
How do carbon ceramic brakes behave on a cold winter morning?
An untuned cold carbon-ceramic disc bites less than cold iron on the first stops. That is basic physics, not a defect. StopFlex tunes both the low-metallic pad compound and the disc's ceramic coating for cold starts, so on your RS7 the first cold-car stops now feel very close to warm summer feel. Leave a little extra following distance on the coldest first pulls and the brakes come up to temperature quickly.
The C8 RS7 came with both iron and factory ceramic brakes. Will this kit fit my exact car?
It fits, but only after we confirm your trim and current setup. This kit is bespoke-engineered per car: the brackets, rotor-hat offsets, and caliper mounting for the Akebono 8N front and TTSPORT EP4 rear are matched to your confirmed C8 RS7 knuckle and hub geometry. We do not assume a platform-wide bolt-on. Send your VIN and we verify whether you are converting from OE iron or replacing OE ceramics before anything is built.
What wheels do I need to clear these rotors?
The front and rear rotors are both 380mm, so the minimum wheel diameter is 19 inches. Wheels under 19 inches will not clear the discs. Spoke shape also matters over the Akebono 6-piston front caliper, so send your exact wheel model and offset and we confirm clearance before we finalize the hat offsets.
Do I lose my electronic parking brake with this rear caliper?
No. The TTSPORT EP4 rear caliper uses a dedicated 27mm actuator piston built specifically to keep the C8's factory electronic parking brake working. You retain OE EPB convenience, including auto-hold, while gaining the thermal capacity of a 4-piston forged big-brake caliper on the 380mm rear rotor.
