Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2008-2014 Audi TT RS / TTS (8J). Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| TT RS | 370mm | 310mm | 19" |
| TTS | 340mm | 310mm | 18" |
Keep Your Factory Calipers?
Keep them if the front calipers are fixed 4-piston or more — the rear axle qualifies regardless. Front 1- or 2-piston floating calipers rule out the disc-only route; choose the Full Upgrade kit instead. Every set is machined to the factory rotor specs listed above, and aftermarket calipers (Brembo, AP Racing, Alcon, Wilwood) only need the caliper model, pad shape, and rotor dimensions confirmed before we build.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
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.
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.
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
Will this fit my TT RS or TTS without changing calipers?
Yes, as long as your front factory calipers are 4-piston or larger. This kit is a direct replacement that reuses your OEM calipers with new carbon-ceramic rotors, hats, pads, and floating hardware. Fitment is trim-specific: the TT RS uses 370mm front and 310mm rear rotors, while the TTS uses 340mm front and 310mm rear. Order the exact set for your trim so the rotor diameters match your factory caliper radial mounts.
How do these brakes behave in winter and cold starts?
Honest answer: any cold carbon-ceramic disc bites a little less than cold iron on the first stops. That's normal physics, not a defect, because the ceramic matrix and pad need a bit of energy before they reach working temperature. We tuned both the low-metallic resin-composite pad and the disc's ceramic coating specifically for cold pickup, so on the 8J the first-stop feel on a cold morning now comes very close to summer feel. Leave a little extra following distance on the very first stops until the front 370mm (TT RS) or 340mm (TTS) rotors take heat, then response is consistent.
Do I need to run bigger wheels to clear these rotors?
No. Because this is a direct replacement that keeps the same factory rotor diameters — 370mm front on the TT RS, 340mm front on the TTS, 310mm rear on both — and reuses your OEM calipers, the package fits inside the same factory wheel envelope your car already runs. Any wheel that cleared your stock brakes clears these.
Is the electronic parking brake affected?
No. The rear 310mm setup on both TT RS and TTS retains the factory parking-brake function using your existing calipers and mechanism. Rear fitment is unrestricted with this kit; only the front calipers need to be 4-piston or larger for the direct replacement to be valid.
