2014-2016 Porsche Cayman (981) / S / GTS / GT4 Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2014-2016 Porsche Cayman (981) / S / GTS / GT4 Carbon Ceramic Brake Kit — OEM-Size Replacement
Owners of the 2014-2016 Porsche Cayman 981 usually shop carbon ceramic brakes for one of two reasons: iron rotors are running hot on track, or factory PCCB rotors have reached replacement cost territory. This StopFlex OEM-size kit matches the listed 315 mm Base, 330 mm S/GTS, 380 mm GT4 iron, or 410 mm GT4 PCCB front setup with the corresponding 299 mm, 380 mm, or 390 mm rear setup, so brake torque and caliper position stay tied to the original Porsche package. Carbon-ceramic rotors reduce dust, resist heat-related fade, and cut rotating unsprung mass where the mid-engine 981 is most sensitive to steering and damper response.
- Built only for 981 Cayman Base, S, GTS, and GT4 brake packages using the rotor sizes listed on this page: 315, 330, 380, or 410 mm front and 299, 380, or 390 mm rear.
- GT4 buyers can replace either the 380/380 mm iron brake package or the 410/390 mm PCCB package without mixing rotor sizes across systems.
- Included pads are compatible with the Porsche OEM pad-wear sensor system, so the factory wear warning remains functional with no brake-warning workaround.

| Rear rotor reference | Base/S/GTS: 299mm; GT4: 380mm, 390mm (PCCB) |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 17" (for the 315 mm rotor) |
For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
This setup uses a 315 mm rotor, so the minimum wheel size is 17". Wheels under 17" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak 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.
Street / Track-Day / Motorsport Rotor Options
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.

FAQ
Will this kit fit every 2014-2016 Cayman 981?
No. Fitment is limited to the exact 981 Cayman Base, S, GTS, and GT4 trim and rotor-size combinations listed for this page. Confirm your current front and rear rotor diameters before ordering: Base 315/299 mm, S/GTS 330/299 mm, GT4 iron 380/380 mm, or GT4 PCCB 410/390 mm.
Does the Porsche brake pad wear warning still work?
Yes. This kit is designed for the 981 Cayman OEM wear-sensor circuit, so the factory pad-wear warning remains active and does not require coding, bypass plugs, or dashboard-error workarounds.
Why replace the 981 Cayman iron brakes with carbon ceramic rotors?
Carbon-ceramic rotors handle repeated heat cycles with less fade than iron, produce much less visible dust on open Porsche wheels, and reduce rotating unsprung mass. On the 981 chassis, that weight reduction is felt at the front axle through steering response and at both axles through damper control.
What should I verify before ordering for a GT4?
Confirm whether your 981 GT4 has the 380/380 mm iron brake package or the 410/390 mm PCCB package. Those systems use different rotor diameters, and this OEM Replacement page does not assume one GT4 brake package fits the other.
Need Fitment Confirmation?
Send the exact vehicle details, current rotor sizes, and caliper type before ordering.
