Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2021-2026+ Porsche 911 (992) Turbo / S. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| Turbo | 408mm, 420mm (PCCB) | 21" | |
| Turbo S | 420mm (PCCB) | 21" | |
| Turbo/S | 380mm, 390mm (PCCB) | 20" | |
| latest Turbo S PCCB rear | 410mm | 21" |
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
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.
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.
Winter & Cold-Weather Braking
A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose 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 these fit my 992 Turbo or Turbo S without changing calipers?
Yes, as long as your car matches the exact factory rotor sizes this page covers. Front fitment applies to the Turbo at 408mm or 420mm (PCCB) and the Turbo S at 420mm (PCCB); rear applies to Turbo/S at 380mm, 390mm, or the latest Turbo S 410mm PCCB rear. The kit reuses your factory 992 calipers, which are 6-piston front units, so the 4-piston-minimum requirement for Direct Replacement is easily met. Confirm your rotor diameter before ordering, since the wrong size will not seat correctly on the factory caliper geometry.
How do these behave in winter or on cold morning starts?
Any carbon-ceramic disc bites less than cold iron on the first stops of the day — that's normal physics, not a fault, and it's true of your factory PCCB too. We optimized both the low-metallic resin-composite pad compound and the disc's ceramic coating specifically for cold starts, so cold-car feel on the 992 now comes very close to summer feel. On the coldest first stops, leaving a little extra following distance until the system reaches temperature is still smart practice.
Why is the dealer quote for factory PCCB replacement so high, and is this genuinely cheaper?
Porsche prices individual PCCB rotors as full assemblies, and the 992 Turbo/S uses large front discs (up to 420mm) plus rears up to 410mm, so a complete four-corner replacement climbs fast at a dealership. This kit gives you carbon-ceramic rotors, pads, hats, and floating hardware while reusing your existing calipers, which removes the most expensive parts from the equation. You get the same braking format the car left the factory with, at a lower total cost.
Will the pad-wear warning still work, or will I get a dashboard error?
The 992 uses electronic brake pad wear sensors, and our pads are 100% compatible with that OEM wear-sensor system. The factory pad-wear warning keeps functioning normally, with no dashboard fault lights or PSM/brake error messages tied to the pad or rotor swap.
