2011-2018 Porsche Cayenne (958) / S / GTS / E-Hybrid CCB Big Brake Kit — Genuine Akebono OEM Porsche 10-Piston (10N) Caliper Front + Genuine Brembo OEM Porsche 19Z 4-Piston Caliper Rear Setup
The 2011-2018 Porsche Cayenne 958 is heavy enough to expose heat, dust, and rotor-cost problems quickly when driven hard, especially on open 21-inch wheels or during repeated mountain and track-day braking. This StopFlex kit replaces the factory brake package with a Genuine Akebono OEM Porsche 10-Piston (10N) Caliper front setup over 420/440mm carbon-ceramic rotors and a Genuine Brembo OEM Porsche 19Z 4-Piston Caliper rear setup over 380mm carbon-ceramic rotors. The payoff is higher thermal capacity, lower rotating mass than comparable iron hardware, reduced brake dust, and trim-specific fitment instead of a platform-wide assumption.
- 420/440mm front carbon-ceramic rotors require 21-inch or larger wheels on the Cayenne 958; wheels under 21 inches will not clear the package, and spoke clearance still must be checked.
- The front axle uses the exact Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, while the rear axle is matched with a Genuine Brembo OEM Porsche 19Z 4-Piston Caliper and 380mm carbon-ceramic rotor.
- Cayenne 958 pad-wear sensors remain compatible with the factory Porsche warning system, so pad monitoring continues 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 axle is built around the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, giving the heavy Cayenne 958 a large multi-piston clamp area for stable pressure distribution and a firm pedal under repeated high-energy stops. Its OEM Porsche-derived provenance matters because the caliper was engineered for large performance-SUV brake loads rather than adapted from a generic aftermarket casting. StopFlex pairs this caliper with the correct 420/440mm carbon-ceramic rotor package, brackets, hats, lines, and hardware 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 larger 10-piston front setup. The Cayenne 958 factory electronic parking brake function is retained with the correctly engineered rear package.
Front & rear, engineered together: This kit is engineered as a complete front-and-rear system so piston area, rotor diameter, pad compound, hat offset, and line routing work together on the customer’s exact Cayenne 958 trim. That avoids the common front-only problem of adding thermal capacity and front torque without matching rear stability and ABS behavior.
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.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |
FAQ
Will this kit fit my exact Cayenne 958 trim?
Fitment is not assumed from the 958 chassis name. StopFlex confirms your year, trim, hub geometry, brake configuration, and wheel specs, then engineers the brackets, rotor-hat offsets, caliper mounting, lines, and hardware for that specific Cayenne / S / GTS / E-Hybrid.
What wheel size is required for the 420/440mm front rotor setup?
The minimum wheel size is 21 inches because the front carbon-ceramic rotor package is up to 420/440mm with the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper. Wheels smaller than 21 inches will not clear, and inner spoke clearance must still be verified before production.
Will the electronic parking brake and pad-wear warnings still work?
Yes. The Cayenne 958 factory electronic parking brake is retained with the rear package, and the kit is compatible with the OEM Porsche brake pad wear-sensor system, so the factory pad-wear warning continues to function without dashboard errors.
Why convert a Cayenne 958 to carbon-ceramic brakes instead of replacing iron rotors?
Carbon-ceramic rotors are chosen when the owner wants lower brake dust, lower rotating mass, better heat resistance under repeated braking, and a large-caliper appearance behind 21-inch or larger wheels. This kit is also a practical alternative for owners comparing dealer-priced OEM carbon-ceramic replacement parts.
