2011-2018 Porsche Cayenne (958) Turbo / S Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2011-2018 Porsche Cayenne (958) Turbo / S Carbon Ceramic Brake Kit — OEM-Size Replacement
The 2011-2018 Cayenne 958 Turbo and Turbo S put high brake energy into large SUV rotors, so owners usually arrive here after heat checking, heavy dust, worn PCCB discs, or repeated iron-rotor service. This StopFlex OEM Replacement kit is built around the exact Turbo 390/358mm or 420/370mm PCCB-size layouts and the Turbo S 420/370mm PCCB layout, replacing the rotors, pads, hats, and floating hardware as a matched system. Carbon-ceramic construction reduces unsprung mass and brake dust while keeping the factory-size fitment envelope for the correct Porsche calipers.
- Covers the Cayenne 958 Turbo 390mm front / 358mm rear setup and the larger 420mm front / 370mm rear PCCB-size setup; Turbo S compatibility is limited to the 420mm front / 370mm rear layout.
- The kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware, so the friction ring and mounting system are replaced together instead of mixing new discs with aged floating components.
- Pad wear sensors are compatible with the Cayenne 958 OEM wear-sensor circuit, so the factory pad-wear warning function remains active without dashboard errors when installed correctly.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Porsche Cayenne (958) Turbo / S |
| Model years | 2011-2018 |
| Front rotor reference | Turbo: 390mm, 420mm (PCCB); Turbo S: 420mm (PCCB) |
| Rear rotor reference | Turbo: 358mm, 370mm (PCCB); Turbo S: 370mm (PCCB) |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 20" (for the 390 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 390 mm rotor, so the minimum wheel size is 20". Wheels under 20" 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 2011-2018 Cayenne 958 Turbo or Turbo S?
No. Fitment is limited to the listed Turbo 390/358mm, Turbo 420/370mm PCCB-size, and Turbo S 420/370mm PCCB-size brake packages. Confirm front and rear rotor diameter, caliper package, VIN/options, and wheel clearance before ordering.
Does the kit keep the factory pad-wear warning system?
Yes. This Cayenne 958 application uses brake pad wear sensors that are compatible with the OEM Porsche wear-sensor system, so the factory warning circuit continues to function with no dashboard error when the sensors are installed and connected correctly.
Why replace the OEM iron or cracked PCCB rotors with carbon ceramic?
On a Cayenne Turbo or Turbo S, the main reasons are lower rotating and unsprung mass, reduced brake dust on open Porsche wheels, better thermal stability under repeated high-speed stops, and a complete rotor-and-pad service path when the original PCCB discs are worn or damaged.
What should I verify before ordering the 420mm front kit?
Verify that your Cayenne 958 uses the 420mm front / 370mm rear PCCB-size package and that your wheels clear the larger front caliper and rotor. The 420mm setup is not interchangeable with the 390mm Turbo front setup without the correct matching hardware and clearance.
