2017-2026+ Porsche 718 Cayman (982) / S / GTS / GT4 RS Carbon Ceramic Brake Kit — OEM-Size Replacement
The 982 Cayman owner shopping OEM-replacement carbon ceramic brakes is usually solving one of two problems: iron-rotor heat and dust on a driven car, or the cost of replacing worn or cracked PCCB discs. This StopFlex kit keeps the factory brake architecture and matches the listed 718 Cayman rotor packages: 330/299 mm and 350/350 mm for Base/T/S/GTS applications, 380/380 mm and 410/390 mm PCCB sizing for GT4, and 408/380 mm or 410/390 mm PCCB sizing for GT4 RS. Carbon-ceramic rotors reduce rotating mass and brake dust while preserving the rotor diameter, caliper position, hats, floating hardware, pads, and Porsche pad-wear sensor function needed for a clean OEM-size replacement.
- Built only for the 2017-2026+ Porsche 718 Cayman 982 trims and rotor sizes listed on this page: Base/T/S/GTS, GT4, and GT4 RS applications are not interchangeable without confirming front and rear disc diameter.
- GT4 and GT4 RS fitments require the correct large-brake package, including 380/380 mm, 410/390 mm, or 408/380 mm rotor references depending on trim and original brake configuration.
- Included pads use brake pad wear sensors compatible with the Porsche OEM wear-sensor circuit, so the factory pad-wear warning remains active with no sensor-related dashboard error when installed correctly.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Porsche 718 Cayman (982) / S / GTS / GT4 RS |
| Model years | 2017-2026+ |
| Front rotor reference | Base/T/S/GTS: 330mm, 350mm (PCCB); GT4: 380mm, 410mm (PCCB); GT4 RS: 408mm, 410mm (PCCB) |
| Rear rotor reference | Base/T/S/GTS: 299mm, 350mm (PCCB); GT4: 380mm, 390mm (PCCB); GT4 RS: 380mm, 390mm (PCCB) |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 17" (for the 330 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 330 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 2017-2026+ 718 Cayman 982?
No. Compatibility is limited to the exact trims and rotor sizes listed for this page. Before ordering, confirm your 982 Cayman trim and measure or verify the current front and rear rotor diameters: Base/T/S/GTS use 330/299 mm or 350/350 mm PCCB references, GT4 uses 380/380 mm or 410/390 mm PCCB references, and GT4 RS uses 408/380 mm or 410/390 mm PCCB references.
Will the Porsche pad-wear warning still work?
Yes. This kit includes pads with wear sensors that are 100% compatible with the OEM Porsche pad-wear sensor system on the 718 Cayman 982, so the factory warning logic stays functional and should not create a dashboard error when the sensors are connected properly.
Why replace the OEM iron or PCCB discs with StopFlex carbon ceramic rotors?
On iron-brake 718 Cayman applications, carbon ceramic reduces brake dust and rotating mass while improving heat stability for repeated high-speed stops. On PCCB-equipped GT4 and GT4 RS cars, this kit replaces expensive carbon-ceramic wear items with OEM-size carbon-ceramic rotors, pads, hats, and floating hardware instead of changing the brake layout.
What should I confirm before ordering for a GT4 or GT4 RS?
Confirm the exact front and rear rotor diameters, caliper package, wheel clearance, and whether the car currently has iron brakes or PCCB-style hardware. GT4 and GT4 RS cars can use different 380 mm, 390 mm, 408 mm, and 410 mm references, and this page only covers the listed OEM-size combinations.
