Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2003-2010 Porsche Cayenne (955. This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2003-2010 | Akebono OEM Porsche 10-Piston (10N) Caliper / 420/440mm | Brembo OEM Porsche 19Z 4-Piston Caliper / 380mm | 21" |
Fitment here is bespoke: brackets, hat offsets, and caliper mounting are engineered for your exact model and trim rather than copied across the platform. Two trims with the same chassis code can still differ in knuckles, hub geometry, and wheel ET clearance — which is why we confirm your trim first, then build the matched system of calipers, pads, rotor hats, floating hardware, and lines for it. Modified knuckles, uprights, or non-factory suspension points require review before ordering.
The 420 mm rotor sets the minimum wheel size at 21" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |
|---|---|
| 15" | 260 mm – 285 mm |
| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |

Why Carbon Ceramic — and Why StopFlex
Short-Fiber or Long-Fiber — Your Call
Every StopFlex disc is true carbon-ceramic. Short-Fiber Street Spec uses a simpler chopped-fiber process for a lower price and street-only duty; the Long-Fiber line uses continuous carbon strands that carry load across the whole rotor for higher strength and thermal durability — the pick for track and race heat.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A like-size carbon-ceramic rotor can be materially lighter than an iron disc; the exact saving depends on rotor dimensions. Lower rotating, unsprung mass can reduce the load the suspension has to control.
High-Temperature Stability
The carbon-silicon-carbide friction material is selected for high-temperature stability and fade resistance. Overall pedal feel still depends on pad condition, fluid, caliper stiffness, cooling and operating temperature.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, carbon-ceramic friction surfaces are designed for low wear. Actual service life depends on mileage, contamination, pad choice, heat cycles and driving use.
Low Visible Dust
Matched StopFlex pads are selected for low visible dust on the ceramic friction surface. Actual wheel dust still varies with pad choice, traffic, temperature, bedding and driving intensity.
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Winter & Cold-Weather Braking
On a freezing start, carbon-ceramic friction can feel different from warm operation. StopFlex pairs the disc coating with its matched street pad to improve cold response; it is still prudent to leave extra margin for the first stops in severe cold. Use a Street Spec for harsh-winter daily service.
Caliper Overview
Front Caliper
The front upgrade uses the Akebono OEM Porsche 10-Piston (10N) Caliper with the supplied 420/440mm rotor configuration. Brackets, hat offsets, and caliper mounting are specified only after exact trim confirmation.
Rear Caliper
The rear upgrade uses the Brembo OEM Porsche 19Z 4-Piston Caliper with 380mm rotors. It is included as part of this full front-and-rear CCB kit.
Choose Your Rotor: Short-Fiber Street to Long-Fiber Motorsport
Pick by how you drive and what you want to spend. Street-only and budget-minded: Short-Fiber Street Spec. Premium street, track days, or competition: one of the three Long-Fiber specs, whose continuous carbon strands carry the strength and heat margin that repeated hard braking demands.
Short-Fiber Street Spec
Chopped short-fiber carbon-ceramic body, ceramic coating, cross-drilled face.
Choose this for street-only use when purchase price matters most. It keeps the carbon-ceramic friction surface and coated finish, but it is not specified for track sessions.
Long-Fiber Street Spec
Continuous long-fiber body, ceramic coating, cross-drilled face, large cooling channels.
Choose this for daily and fast-road use when you want the long-fiber construction without moving to a track-focused face and cooling specification.
Long-Fiber Track-Day Spec
Continuous long-fiber body, ceramic coating, blank face, honeycomb cooling channels.
Choose this for repeated fast-road or track-day braking where thermal duty matters more than the drilled street appearance. High-temperature fluid and appropriate cooling still matter.
Long-Fiber Motorsport Spec
Continuous long-fiber body, uncoated blank face, honeycomb cooling channels.
Choose this for competition-focused use with the corresponding pad, fluid, cooling and warm-up strategy. It is not the default recommendation for a street-driven car.
Heat Management Note
Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.
Get Your Fitment Confirmed
Before ordering, provide the exact vehicle, current rotor sizes, caliper type, and wheel details. Production starts only after the configuration is confirmed; VIN/build data is requested when it is needed to resolve fitment.
FAQ
Does this kit fit every 2003-2010 Cayenne 955/957?
No. This listing is for the 2003-2010 Porsche Cayenne 955/957 family, but the kit is bespoke to the confirmed model and trim. The Akebono OEM Porsche 10-Piston (10N) front and Brembo OEM Porsche 19Z 4-Piston rear setup require trim-specific confirmation of brackets, hat offsets, and caliper mounting before ordering.
Will my wheels clear the 420mm front setup?
The 420mm front configuration has a 21-inch minimum wheel requirement in the fitment chart. Diameter alone is not enough: wheel spoke profile and offset still need physical clearance confirmation. Submit the exact wheel details before the kit is specified; do not assume clearance from another 955/957 trim or shared platform.
Which rotor specification should I choose for my Cayenne?
Choose Short-Fiber Street Spec for lower-cost street-only use. Long-Fiber Street suits higher-demand road use, while Long-Fiber Track-Day and Motorsport are for progressively greater heat and duty requirements. Confirm how the vehicle is used before ordering so the rotor specification matches the intended service rather than simply selecting the highest option.
What should I expect on cold or winter first stops?
An untuned cold carbon-ceramic disc can have less initial bite than cold iron. This kit uses a matched pad compound and disc coating tuned to reduce that cold-start gap, but the coldest first stops still deserve extra margin. Allow the brakes to come up to temperature before expecting normal response.
