As automotive technology evolves, discerning owners are increasingly focused on upgrading their braking systems to match the performance of modern supercars. For the Porsche Cayenne (92A), a vehicle known for its robust engineering but substantial weight, the factory steel brakes can be a limiting factor.
STOPFLEX carbon-ceramic rotors have become a top choice for high-end retrofits. They offer a transformative improvement in performance, durability, and compatibility. This owner decided to go all-in, moving from factory steel discs to a bespoke Akebono 10-Piston setup paired with STOPFLEX Carbon-Ceramics, proving that an older platform can still dominate the road.
The Bespoke 10-Piston Build
This build utilizes a custom combination of elite aftermarket calipers and our advanced rotors to create a braking system capable of handling the Cayenne's mass with ease, fitting inside the 20-inch wheels.
- Vehicle: Porsche Cayenne (92A)
- Front Calipers: Akebono 10-Piston Fixed Calipers
- Front Rotors: STOPFLEX 420mm (16.5 in) Carbon-Ceramic Discs
- Rear Calipers: Brembo 4-Piston Fixed Calipers
- Rear Rotors: STOPFLEX 380mm (15.0 in) Carbon-Ceramic Discs
- Brake Pads: STOPFLEX High-Performance Ceramic Pads
- Hardware: Custom mounting bolts and brackets
Important: System Compatibility
This case study features a bespoke Big Brake Kit (BBK) conversion using aftermarket fixed multi-piston calipers (Akebono & Brembo). Our STOPFLEX carbon-ceramic rotors are engineered for this specific type of high-performance setup.
Please note: These rotors cannot be directly installed with factory floating calipers. A fixed caliper setup is required to utilize these high-performance discs.
Key Advantages for the Cayenne 92A
- Massive Thermal Capacity: The Akebono 10-piston caliper provides immense clamping force. Paired with our 420mm (16.5 in) carbon-ceramic rotor, the system offers consistent friction performance even under extreme thermal loads. This ensures reliability during high-speed stops or heavy braking events.
- Transformative Weight Reduction: STOPFLEX carbon-ceramic discs are over 50% lighter than comparable steel rotors. Reducing this unsprung mass ("1kg of unsprung weight is worth 10kg of sprung weight") sharpens the Cayenne's handling, improves acceleration, and allows the suspension to react faster to road imperfections.
- Extraordinary Durability: Engineered for longevity, these rotors offer a service life that far exceeds traditional iron discs. The corrosion-proof material ensures the rotors remain pristine, avoiding the unsightly rust that can plague steel brakes, especially in wet climates.

Frequently Asked Questions
Q: Why combine Akebono and Brembo calipers?
A: This bespoke configuration optimizes performance for the Cayenne's weight distribution. The 10-piston Akebono front caliper offers maximum clamping force for the heavy front end, while the Brembo rear caliper provides a reliable, balanced solution for the rear axle.
Q: Will a 420mm rotor fit inside my 20-inch wheels?
A: Yes, but it is a tight fit. This kit is engineered with compact caliper profiles to maximize rotor size (420mm) while maintaining clearance for most high-performance 20-inch wheels. It fills the wheel barrel completely for a purposeful look.
Q: Is this system suitable for street driving?
A: Absolutely. Despite the race-grade hardware, the system is engineered for refined street performance. The pads provide excellent cold bite and smooth modulation, making the car easy to drive in traffic while being ready for any performance demand.
