Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2019-2026+ Porsche Cayenne (9Y0) / S / E-Hybrid. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| Base/E-Hybrid | 350mm | 18" | |
| S/S E-Hybrid | 390mm | 20" | |
| PSCB option | 415mm | 365mm | 21" |
| Base/E-Hybrid/S/S E-Hybrid | 330mm | 17" |
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
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
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.

Before ordering, tell us the exact vehicle, current rotor sizes, and caliper type. Nothing goes to production until the build is confirmed against your VIN-level configuration.
FAQ
Does this fit my exact Cayenne trim?
This page covers the 9Y0 Cayenne, Cayenne S, and their E-Hybrid variants only. Front rotors match 350mm on Base and E-Hybrid, and 390mm on S and S E-Hybrid; rear rotors are 330mm across all four. If your car has the PSCB option (415mm front / 365mm rear) or the Turbo/Turbo GT setup, this kit is not the correct fit. Direct replacement is only valid because the factory front calipers on these trims are 4-piston or more, so we retain them and swap only the discs, pads, hats, and floating hardware. Confirm your rotor diameter before ordering.
How does this compare to a factory PCCB replacement?
It's the same job at a fraction of the parts bill. Porsche PCCB rotors are a maintenance item, and a fresh set from the dealer runs into five figures. Our carbon-ceramic discs are built to the same 350mm/390mm front and 330mm rear dimensions and bolt to your existing Cayenne calipers, so there's no caliper swap and no brake-line change. You keep the OEM ride, feel, and packaging while replacing worn rotors for far less.
Will the pad-wear warning still work?
Yes. The Cayenne uses electronic brake pad wear sensors, and our pads are 100% compatible with that OEM wear-sensor system. The factory dashboard pad-wear warning keeps functioning normally with no fault codes or error lights. The compound is a carbon-ceramic-specific low-metallic resin composite with steel, copper, and aramid fiber, averaging a 0.44 coefficient of friction and holding up to about 750 °C with strong anti-fade behavior.
How do these behave in winter and cold starts?
Honestly: any cold carbon-ceramic disc bites a little less than cold iron on the first stop. That's physics, not a defect. We tuned both the pad compound and the disc's ceramic coating specifically for cold starts, so on your first winter stop in a 9Y0 the feel now comes very close to warm summer braking. It's still smart to leave a little extra following distance on the coldest first few stops until everything is up to temperature.
