2003-2010 Porsche Cayenne (955 / 957) Turbo / S 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 Turbo / S is heavy, fast, and hard on iron rotors when driven in mountains, towing conditions, or repeated high-speed braking. This StopFlex kit replaces the factory-style setup with 420/440mm front carbon-ceramic rotors, Genuine Akebono OEM Porsche 10-Piston (10N) Caliper front calipers, 380mm rear carbon-ceramic rotors, and Genuine Brembo OEM Porsche 19Z 4-Piston Caliper rear calipers. The result is more heat capacity at the front axle, lower rotating and unsprung mass than comparable iron hardware, reduced brake dust, and fitment engineered around the customer’s exact 955 / 957 Turbo or S trim rather than a generic Cayenne assumption.
- 420mm is the largest front rotor size in this kit, so 21-inch wheels are the minimum; wheels under 21 inches will not clear, and spoke clearance must still be checked.
- The front axle uses the exact Genuine Akebono OEM Porsche 10-Piston (10N) Caliper with 420/440mm carbon-ceramic rotors for the heat load of a V8 Cayenne Turbo / S.
- The kit keeps the Cayenne brake pad wear-sensor function compatible with the factory Porsche warning system, so pad monitoring remains active 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.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front upgrade uses the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, giving the heavy Cayenne Turbo / S a broad pad load area and firm pedal response under repeated high-energy stops. Because it is a genuine OEM-derived Porsche caliper rather than a generic aftermarket casting, the package is built around proven caliper architecture and StopFlex-specific carbon-ceramic rotor, hat, bracket, and line engineering. Front rotor sizing is configured as 420/440mm during order engineering for the confirmed vehicle and wheel package.
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 contribution matched to the larger front system. It supports brake stability and bias balance instead of leaving the rear axle as an under-capacity iron setup behind a much larger front conversion.
Front & rear, engineered together: StopFlex engineers the front and rear package together so piston area, rotor diameter, hat offset, bracket position, pad selection, and hydraulic lines work as one system. That matters on the 955 / 957 Cayenne because an oversized front-only conversion can shift bias too far forward and leave the rear axle thermally and visually mismatched.
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 2003-2010 Cayenne Turbo or S?
Fitment is confirmed per vehicle before production. StopFlex matches the brackets, rotor-hat offsets, caliper mounting, and line routing to your exact 955 / 957 Turbo or S trim instead of treating every Cayenne chassis as the same.
What wheel size do I need for the 420/440mm front setup?
The minimum wheel size is 21 inches because the largest front rotor in this kit is 420mm. Wheel diameter alone is not enough; spoke shape, barrel profile, and wheel ET must also clear the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper.
Does this Cayenne kit retain the factory electronic parking brake?
The 2003-2010 Cayenne 955 / 957 does not use a factory electronic parking brake. This rear brake package is engineered around the vehicle’s mechanical parking-brake layout, and the pad wear sensors remain compatible with the Porsche warning system.
Why choose carbon-ceramic instead of another iron big brake kit?
Carbon-ceramic rotors reduce rotating and unsprung mass compared with similar-size iron rotors, produce less visible brake dust, and maintain more consistent braking behavior under repeated heat cycles. On a heavy Cayenne Turbo / S, the main payoff is heat management without adding more iron mass at the corners.
