Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2019-2026+ Audi RS Q3 (F3). Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| RS Q3 | 375mm, 380mm (CCB) | 310mm | 19" |
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
Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.

FAQ
Will this fit my RS Q3 if it already has the factory 380mm carbon-ceramic front discs?
Yes. This page covers the F3 RS Q3 with factory front rotors of 375mm or 380mm (the 380mm being the OEM carbon-ceramic option) and 310mm rears. Because the RS Q3 runs a 4-piston front caliper, the direct-replacement discs bolt to your existing calipers using the supplied hats and floating hardware. If you have the iron 375mm front setup, you get the carbon-ceramic upgrade; if you already run the 380mm CCB, these are your replacement discs. Confirm your exact front size before ordering.
How do these behave in winter and on cold starts?
Physics first: any cold carbon-ceramic disc bites a little less than cold iron until it warms, and that is normal, not a fault. We addressed it two ways on this kit — the low-metallic resin-composite pad compound and the disc's ceramic coating are both tuned for cold engagement. The result is that first-stop feel on a cold RS Q3 now comes very close to summer feel. On the coldest first stops of the day, still leave a bit of extra following distance until the front discs come up to temperature.
Why does the factory RS Q3 brake feel go soft on track, and does this fix it?
The stock iron front discs on the F3 reach their heat ceiling after a few hard laps, and once the pads and fluid soak that heat you get a long, soft pedal. Carbon-ceramic discs hold far more heat before fade and shed it faster. Paired with our pad rated to about 750 °C with strong anti-fade behavior and an average friction coefficient near 0.44, the pedal stays firm well past the point where the iron setup gives up.
Do I keep my factory calipers and does this work with the electronic parking brake?
Yes to both. This is a direct-replacement disc kit that reuses your factory RS Q3 front and rear calipers — you swap only the rotors, hats, pads, and hardware. The rear 310mm assembly is designed around the F3's electronic parking brake, so the EPB continues to operate normally. Check your wheel clearance against the supplied disc and hat dimensions before installing.
