Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2005-2012 Porsche Boxster (987) / S / Spyder. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| Base | 298mm | 16" | |
| S/Spyder | 318mm, 350mm (PCCB) | 18" | |
| Base/S/Spyder | 299mm, 350mm (PCCB) | 18" |
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
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.
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.
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.
Get Your Fitment Confirmed
Send the exact vehicle details, current rotor sizes, and caliper type before ordering. Every StopFlex order is confirmed against your VIN-level configuration before production.
FAQ
Does this kit fit my exact 987 Boxster trim?
This page covers the 2005-2012 Boxster, Boxster S, and Spyder (987) only, and fitment is tied to the exact factory rotor sizes listed: Base fronts are 298mm, S/Spyder fronts are 318mm (or 350mm on PCCB cars), and all rears are 299mm (or 350mm PCCB). Direct Replacement requires your front factory calipers to be 4-piston or more, which the S and PCCB cars carry. Match your car's rotor diameter and caliper count before ordering, and confirm with us if you're unsure which setup left the factory on your VIN.
How do these perform on a cold winter start?
Any carbon-ceramic disc bites a little less than cold iron on the first stops of a cold morning. That's physics, not a defect. StopFlex tunes both the low-metallic resin-composite pad and the disc's ceramic coating specifically for cold engagement, so on the 987 the cold-car feel now comes very close to warm-summer feel after just a corner or two. On the coldest first stops, leave a little extra following distance until the front discs take heat, then they behave normally.
Will the factory pad-wear warning still work?
Yes. The included pads carry wear sensors that are 100 percent compatible with the Porsche OEM wear-sensor system on the 987, so your dash pad-wear warning keeps functioning with no fault codes or warning-light errors. This is a common worry on PCCB cars, and it's handled — the sensor plugs into the factory harness exactly like the original.
Why replace PCCB instead of resurfacing my old rotors?
Carbon-ceramic discs can't be machined back to spec the way steel rotors can. Once the reinforced friction layer wears through, the whole disc is done. This kit gives you new carbon-ceramic rotors, pads, hats, and floating hardware while reusing your existing 987 calipers, so you restore full PCCB performance without buying new calipers or converting to iron.
