2003-2010 Porsche Cayenne (955 / 957) / S / GTS CCB Big Brake Kit — Genuine Akebono OEM Porsche 10-Piston (10N) Caliper Front + Genuine Brembo OEM Porsche 19Z 4-Piston Caliper Rear Setup
The 2003-2010 Cayenne 955/957 is heavy enough to expose heat fade, rotor stress, and brake dust quickly when driven hard, especially on open 21-inch wheels. This StopFlex kit replaces the factory brake package with Genuine Akebono OEM Porsche 10-Piston (10N) front calipers over 420/440mm carbon-ceramic front rotors and Genuine Brembo OEM Porsche 19Z rear calipers over 380mm rear carbon-ceramic rotors. Each kit is built to the customer’s exact Cayenne, Cayenne S, or GTS trim so the bracket geometry, rotor-hat offset, and caliper position match the specific vehicle instead of relying on a platform-wide assumption.
- 420/440mm front carbon-ceramic rotors require 21-inch or larger wheels on the Cayenne 955/957; wheels under 21 inches will not clear, and spoke clearance must still be verified.
- Front braking is handled by the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, paired with StopFlex carbon-ceramic rotors for higher heat capacity and lower brake dust than iron rotors.
- The kit keeps the Porsche pad-wear warning system functional with compatible wear sensors, so the factory brake-pad warning logic continues to work without dashboard errors.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 420 mm front rotor, so the minimum wheel size is 21". Wheels under 21" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |

| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |

| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |
Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, giving the Cayenne a large multi-piston clamp package suited to the mass and front brake load of the 955/957 chassis. Its OEM Porsche provenance gives the kit a credible caliper foundation rather than an unproven universal aftermarket casting. StopFlex pairs it with the correct 420/440mm carbon-ceramic rotor, hat, bracket, hardware, pads, and lines for the confirmed trim.
Rear Caliper (Balance)
The rear axle uses the Genuine Brembo OEM Porsche 19Z 4-Piston Caliper with a 380mm carbon-ceramic rotor to keep rear torque contribution matched to the front upgrade. This helps maintain braking stability instead of leaving the rear axle under-capacity after a major front brake increase.
Front & rear, engineered together: The front and rear packages are engineered together so rotor diameter, caliper position, pad compound, and hydraulic behavior are treated as a system. That matters on the Cayenne 955/957 because a front-only increase can shift brake balance forward and reduce the rear axle’s contribution under repeated high-energy stops.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

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.
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 my exact Cayenne, Cayenne S, or GTS?
Fitment is confirmed per vehicle before build. StopFlex matches the brackets, rotor-hat offsets, caliper mounting, and line routing to the exact 2003-2010 Cayenne 955/957 trim, not just the shared chassis code.
What wheels do I need for the 420/440mm front rotor setup?
The largest front rotor in this kit is 420mm, so the minimum wheel size is 21 inches. Wheels under 21 inches will not clear, and StopFlex still checks spoke clearance, wheel offset, and caliper face clearance before finalizing the kit.
Does this Cayenne have an electronic parking brake to retain?
No. The 2003-2010 Cayenne 955/957 uses a foot-operated mechanical parking brake, so there is no EPB motor or electronic rear parking-brake actuator to integrate. The rear package is built around the Cayenne’s mechanical parking-brake layout.
Will the factory brake pad wear warning still work?
Yes. This Porsche kit includes brake pad wear sensors that are compatible with the OEM wear-sensor system, so the factory pad-wear warning remains active without dashboard errors.
