Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2019-2026+ Audi RS7 / S7 (C8). Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| RS7 | 420mm, 440mm (CCB) | 370mm | 22" |
| S7 | 400mm | 350mm | 20" |
Keep Your Factory Calipers?
Yes — if your front factory calipers are fixed 4-piston or more. The rear axle has no restriction. Cars with 1- or 2-piston floating front calipers should use the Full Upgrade kit (calipers + discs) instead. Discs are built to the factory rotor specs shown above; if you run aftermarket calipers (Brembo, AP Racing, Alcon, Wilwood), we simply confirm the caliper model, pad shape, and rotor dimensions before production.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
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.
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.
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.
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
How do these carbon ceramic rotors behave in winter or on a cold start?
Cold physics are real: an untuned carbon-ceramic disc bites a little less than cold iron on the first stops of the day. That is normal, not a fault. We addressed it two ways on this C8 kit — the resin-composite pad compound and the disc's ceramic coating are both tuned for cold engagement, so the winter cold-car feel now comes very close to summer feel. On the coldest first pulls out of the driveway, leave a bit of extra following distance until the front rotors take heat, then the RS7/S7 pedal firms up as expected.
Will this fit my exact RS7 or S7 without changing calipers?
This is a direct replacement that reuses your factory C8 calipers, so fitment is trim- and size-specific. RS7 front rotors are 420mm or 440mm (the 440mm is the factory CCB size); RS7 rear is 370mm. S7 front is 400mm; S7 rear is 350mm. You must match the exact front rotor diameter on your car. Direct replacement is only valid when the front factory calipers are 4-piston or more; the rear is unrestricted. Confirm your front rotor size before ordering.
Why is this so much cheaper than the Audi dealer quote for factory CCBs?
Dealer replacement of all four factory carbon-ceramic rotors on a C8 RS7 can run near the tens of thousands because you are buying full OEM assemblies through the parts channel. This kit gives you carbon-ceramic rotors, pads, hats, and floating hardware that bolt to the calipers you already own. You keep the C8 caliper bodies and pistons, so you are not paying to replace parts that are still good.
Can I track my C8 with these, or are they street-only?
Both. The pad is a carbon-ceramic-specific low-metallic resin-composite with steel, copper, and aramid fiber, averaging about a 0.44 coefficient of friction with heat resistance to roughly 750 °C and strong anti-fade behavior. On the RS7's 420mm/440mm front and S7's 400mm front, that supports repeated hard stops on track days while staying quiet and low-dust for daily driving. Choose the rotor tier that matches how you actually use the car.
