Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2022-2027 Porsche 911 (992) GT3 / RS / S/T / Sport Classic. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| GT3/Touring/GT3 RS/S/T | 408mm, 410mm (PCCB) | 380mm, 390mm (PCCB) | 21" |
| GT3 S/C | 410mm (PCCB std.) | 390mm (PCCB std.) | 21" |
Keep Your Factory Calipers?
The rule is simple: front factory calipers must be 4-piston or more; the rear has no limit. A 1- or 2-piston floating front setup cannot take direct-replacement discs — that car needs the Full Upgrade kit with calipers. We build to the factory rotor specs above. Aftermarket calipers (Brembo, AP Racing, Alcon, Wilwood) work too — send the caliper model, pad shape, and rotor size for confirmation first.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
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.
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.
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
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.

FAQ
Will these fit my 992 GT3 or GT3 RS with the factory PCCB calipers?
Yes, as long as your car is one of the listed trims and your factory front rotors measure 408mm or 410mm and rears 380mm or 390mm. These are direct-replacement carbon-ceramic discs that reuse your factory PCCB calipers, so the front caliper must be the 4-piston (or larger) unit these cars ship with. If you own the GT3 S/C variant, your car came with 410mm front and 390mm rear PCCB as standard and is covered. Confirm your exact rotor diameter before ordering.
How is this different from paying Porsche for new PCCB rotors?
You get the same carbon-ceramic construction the 992 relies on, but you keep your factory calipers and hats' function and only replace the wear items. The kit ships as carbon-ceramic rotors, pads, hats, and floating hardware, so you are not paying for a full brake system you already own. The pad wear sensors are 100% compatible with the OEM wear-sensor system, so your factory pad-wear warning still works with no dashboard errors.
How do these behave on cold winter mornings compared to iron brakes?
An untuned cold carbon-ceramic disc bites less than cold iron on the first few stops. That is physics, not a defect. We tuned both the pad compound and the disc's ceramic coating for cold starts, so on a cold 911 the first-stop feel now comes very close to summer feel. Leave a little extra following distance on the coldest initial stops until the front discs come up to temperature, then behavior is normal.
What pads come with the kit and how much heat do they handle?
The included pads use a carbon-ceramic-specific low-metallic resin-composite compound with steel, copper, and aramid fiber, with an average coefficient of friction around 0.44 and heat resistance to about 750 °C with strong anti-fade behavior. That range suits the way these 992 GT3-family cars are driven, from street commuting to sustained track sessions on the 408-410mm front discs.
