2003-2010 Porsche Cayenne (955 / 957) / S / GTS Carbon Ceramic Brake Kit — OEM-Size Replacement
The 2003-2010 Cayenne 955/957 is heavy enough to turn iron rotors into a heat-management problem, especially on mountain descents, towing, and repeated high-speed braking. This OEM-size StopFlex kit matches the factory brake package for each listed trim—330 mm front Base/Diesel, 350 mm front S, 368 mm front GTS, and 330 mm rear Base/S/GTS/Diesel—so the carbon-ceramic rotors, pads, hats, and floating hardware work with the original caliper layout. The result is lower rotating mass, cleaner open wheels, stronger fade resistance, and factory pad-wear warning compatibility with no dashboard errors.
- Front rotor sizing follows the Cayenne trim: 330 mm for Base/Diesel, 350 mm for S, and 368 mm for GTS; rear rotors are 330 mm on the listed Base/S/GTS/Diesel fitments.
- Includes carbon-ceramic rotors, matched pads, hats, and floating hardware for an OEM-size replacement rather than a caliper-conversion kit.
- Integrated pad wear sensor compatibility keeps the 955/957 Cayenne factory pad-wear warning system active after the brake conversion.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Porsche Cayenne (955 / 957) / S / GTS |
| Model years | 2003-2010 |
| Front rotor reference | Base/Diesel: 330mm; S: 350mm; GTS: 368mm |
| Rear rotor reference | Base/S/GTS/Diesel: 330mm |
| 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 2003-2010 Porsche Cayenne?
No. This page is limited to the listed 955/957 Cayenne Base, Diesel, S, and GTS brake packages with the stated rotor sizes: 330 mm front Base/Diesel, 350 mm front S, 368 mm front GTS, and 330 mm rear Base/S/GTS/Diesel. Confirm the rotor diameter on the car before ordering.
Does the StopFlex kit change the calipers or parking brake system?
No. This is an OEM-size rotor replacement kit with carbon-ceramic rotors, pads, hats, and floating hardware. It is designed around the original Cayenne caliper and rear parking-brake layout for the compatible rotor package.
Will the Porsche brake pad wear warning still work?
Yes. This Cayenne kit uses brake pad wear sensors that are 100% compatible with the OEM wear-sensor system, so the factory pad-wear warning remains functional without dashboard errors.
Why switch this Cayenne from iron rotors to carbon-ceramic?
Carbon-ceramic rotors reduce rotating and unsprung mass, cut brake dust, and handle repeated heat cycles better than iron rotors. On a 955/957 Cayenne, those benefits matter because the vehicle’s weight puts high thermal load into the front brakes.
