Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2014-2016 Porsche Cayman (981) / S / GTS / GT4. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| Base | 315mm | 17" | |
| S/GTS | 330mm | 17" | |
| GT4 | 380mm, 410mm (PCCB) | 380mm, 390mm (PCCB) | 21" |
| Base/S/GTS | 299mm | 16" |
Keep Your Factory Calipers?
Keep the factory calipers when the front axle uses fixed 4-piston-or-larger calipers; the rear axle has no piston-count restriction. Front 1- or 2-piston floating calipers require a Full Upgrade kit. Aftermarket-caliper applications are not assumed to fit: StopFlex reviews the caliper model, pad shape, rotor dimensions and offset before approving the build.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
Long Street-Service Life
In normal road use with matched pads and correct bedding, carbon-ceramic friction surfaces are designed for low wear. Actual service life depends on mileage, contamination, pad choice, heat cycles and driving use.
Low Visible Dust
Matched StopFlex pads are selected for low visible dust on the ceramic friction surface. Actual wheel dust still varies with pad choice, traffic, temperature, bedding and driving intensity.
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.
Short-Fiber or Long-Fiber — Your Call
Every StopFlex disc is true carbon-ceramic. Short-Fiber Street Spec uses a simpler chopped-fiber process for a lower price and street-only duty; the Long-Fiber line uses continuous carbon strands that carry load across the whole rotor for higher strength and thermal durability — the pick for track and race heat.
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 like-size carbon-ceramic rotor can be materially lighter than an iron disc; the exact saving depends on rotor dimensions. Lower rotating, unsprung mass can reduce the load the suspension has to control.
High-Temperature Stability
The carbon-silicon-carbide friction material is selected for high-temperature stability and fade resistance. Overall pedal feel still depends on pad condition, fluid, caliper stiffness, cooling and operating temperature.
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.
Winter & Cold-Weather Braking
Cold-weather trade-off: an untuned carbon-ceramic disc can have less initial bite than cold iron. StopFlex specifies a matched pad compound and ceramic coating tuned to reduce that cold-start gap, but the coldest first stops still deserve extra following distance. Severe-winter daily drivers should choose a Street Spec.
Choose Your Rotor: Short-Fiber Street to Long-Fiber Motorsport
Pick by how you drive and what you want to spend. Street-only and budget-minded: Short-Fiber Street Spec. Premium street, track days, or competition: one of the three Long-Fiber specs, whose continuous carbon strands carry the strength and heat margin that repeated hard braking demands.
Short-Fiber Street Spec
Chopped short-fiber carbon-ceramic body, ceramic coating, cross-drilled face.
Choose this for street-only use when purchase price matters most. It keeps the carbon-ceramic friction surface and coated finish, but it is not specified for track sessions.
Long-Fiber Street Spec
Continuous long-fiber body, ceramic coating, cross-drilled face, large cooling channels.
Choose this for daily and fast-road use when you want the long-fiber construction without moving to a track-focused face and cooling specification.
Long-Fiber Track-Day Spec
Continuous long-fiber body, ceramic coating, blank face, honeycomb cooling channels.
Choose this for repeated fast-road or track-day braking where thermal duty matters more than the drilled street appearance. High-temperature fluid and appropriate cooling still matter.
Long-Fiber Motorsport Spec
Continuous long-fiber body, uncoated blank face, honeycomb cooling channels.
Choose this for competition-focused use with the corresponding pad, fluid, cooling and warm-up strategy. It is not the default recommendation for a street-driven car.
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.
Get Your Fitment Confirmed
Before ordering, provide the exact vehicle, current rotor sizes, caliper type, and wheel details. Production starts only after the configuration is confirmed; VIN/build data is requested when it is needed to resolve fitment.
FAQ
Which 2014-2016 Porsche Cayman (981) brake configurations does this listing cover?
This listing is limited to 2014-2016 Porsche Cayman (981), Cayman S, GTS and GT4 configurations with the supplied rotor references: front 315 mm Base, 330 mm S/GTS, and 380 mm or 410 mm PCCB GT4; rear 299 mm Base/S/GTS and 380 mm or 390 mm PCCB GT4. Front factory calipers must be fixed four-piston or larger. The rear axle has no caliper restriction.
Do I keep the factory calipers on my Cayman 981?
Yes. This is a Direct Replacement configuration that retains the factory calipers. The package includes StopFlex CCB rotors, matched pads, vehicle-specific rotor hats and floating hardware. It also includes brake-pad wear sensors specified as compatible with the OEM wear-sensor system for this product. Confirm the front rotor reference and that your front calipers are fixed four-piston or larger before ordering.
Which StopFlex rotor specification suits my Cayman 981 use?
Choose Short-Fiber Street Spec for lower-cost street-only use. Long-Fiber Street is the next step for road use with greater duty requirements. Track-Day and Motorsport use long-fiber construction for progressively higher heat demands. Select the rotor specification around how the car is actually driven; the supplied Cayman 981 rotor size and factory-caliper eligibility still determine whether this Direct Replacement configuration applies.
What should I expect from carbon-ceramic brakes in cold winter conditions?
An untuned cold carbon-ceramic disc can have less initial bite than cold iron. StopFlex specifies a matched pad compound and disc coating to reduce that cold-start gap, but the coldest first stops still deserve extra margin. This applies whether your Cayman uses the 315 mm Base, 330 mm S/GTS, or GT4 rotor references covered by this listing.
