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 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 |

Why Carbon Ceramic — and Why StopFlex
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.
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.
Winter & Cold-Weather Braking
Cold facts first: an untuned ceramic disc bites less than iron on a freezing morning — physics, not a defect. StopFlex tuned both the pad compound and the disc's ceramic coating for cold starts, so winter cold-car braking now feels very close to summer. Leave extra margin on the very coldest first stops; severe-climate daily drivers should build Street Spec.
Caliper Overview
Front Caliper
The front caliper is the Akebono OEM Audi RS 6-Piston (9N) unit — genuine factory RS hardware with six pistons per side. It delivers OE-level clamping and repeatable pedal feel over the 400mm carbon-ceramic front rotor without the guesswork of an unproven aftermarket body.
Rear Caliper
The rear runs the TTSPORT EP4 4-Piston Forged Caliper, which pairs four 28 mm hydraulic service pistons with a dedicated 27 mm EPB actuator piston so your factory electronic parking brake still works exactly as it did. Its two-piece forged-aluminum body (about 4.50 kg per caliper without pads) and heat-insulated pistons add real rear-axle thermal capacity behind the 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
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
Will these brakes work in the cold, or do carbon ceramics stay grabby-free until they warm up?
An untuned cold carbon-ceramic disc bites a little less than cold iron — that's normal physics, not a fault. On this kit we've tuned both the pad compound and the disc's ceramic coating for cold starts, so first-thing-in-the-morning braking feel on your RS7 comes very close to summer feel. Leave a bit of extra following distance on the coldest first few stops and you'll be fine.
How do I know this fits my exact RS7 and not just the C8 platform?
We build every kit bespoke to your confirmed trim. The brackets, rotor-hat offsets, and caliper mounting are machined for your specific RS7 (C8) — hub geometry and wheel ET clearance can differ across the RS family, so we don't assume a platform-wide bolt-on fit. Once you confirm your VIN and current brake package, the parts are matched to that car.
What wheel size do I need to clear the 400mm front rotor?
The front rotor is 400mm, so 20-inch wheels are the minimum up front — anything under 20 inches will not clear it. Spoke clearance matters too, especially around the Akebono 9N caliper, so send us your wheel spec when you confirm fitment and we'll check it against the caliper envelope.
Does the rear caliper keep my electronic parking brake?
Yes. The TTSPORT EP4 has a dedicated EPB actuator piston separate from its four hydraulic braking pistons, so your factory electronic parking brake keeps working normally. You gain real rear-axle thermal capacity over the 380mm rotor without losing OE parking-brake convenience or throwing dash faults.
