Why are so many Porsche Cayenne owners choosing to upgrade to the STOPFLEX Carbon-Ceramic Brake System? The reason is simple: an uncompromising pursuit of performance and safety. For those who didn't tick the expensive "PCCB" box at the dealership, the factory steel brakes can feel like the limiting factor on such a capable, heavy vehicle.
STOPFLEX offers a proven solution with extensive installation data. We provide a system that rivals the factory carbon-ceramics, delivering superior braking bite, a more agile pedal feel, and significantly reduced vehicle weight, all backed by mature technical support.
The Bespoke Upgrade Plan
This build features a custom "best-of-breed" configuration, utilizing massive 10-piston front calipers to manage the Cayenne's momentum, all fitting within the 22-inch wheels.
- Vehicle: Porsche Cayenne Coupe (9Y3)
- Front Calipers: Akebono 10-Piston Fixed Calipers
- Front Rotors: STOPFLEX 440mm (17.3 in) Carbon-Ceramic Discs
- Rear Calipers: Brembo 4-Piston Fixed Calipers
- Rear Rotors: STOPFLEX 410mm (16.1 in) Carbon-Ceramic Discs
- Brake Pads: STOPFLEX High-Performance Ceramic Pads
- Accessories: Custom mounting bolts and hardware
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 of this Bespoke System
- PCCB-Level Performance: This system delivers the elite braking characteristics of the factory Porsche Ceramic Composite Brakes—immense fade resistance and longevity—but at a much more accessible value point. It is the smart choice for owners seeking top-tier performance without the dealer markup.
- Transformative Weight Reduction: STOPFLEX carbon-ceramic discs are over 40% lighter than comparable steel rotors. Reducing this unsprung mass sharpens the Cayenne's turn-in, improves suspension compliance, and makes the SUV feel significantly more agile.
- Enhanced Pedal Feel: The combination of the rigid 10-piston caliper and the carbon-ceramic rotor provides a linear, sensitive pedal feel. It allows for precise modulation, giving the driver complete confidence whether commuting or driving spiritedly.
- Mirror-Finish Durability: Our rotors are engineered for extraordinary longevity. Over time, the friction surface develops a mirror-like finish that is highly wear-resistant, often lasting the lifetime of the vehicle under normal use.

Frequently Asked Questions
Q: Why use Akebono 10-piston calipers on a Cayenne?
A: This setup mimics the braking hardware found on the "Super SUV" platform mates like the Lamborghini Urus and Audi RSQ8. The 10-piston caliper provides the massive clamping force and pad surface area required to stop a heavy, high-performance SUV repeatedly without fade.
Q: Is this system reliable for daily driving?
A: Absolutely. The system is engineered for refined street performance. The pads are formulated to provide excellent bite from cold temperatures, and the rotors are corrosion-proof, meaning no rusty discs after parking in the rain.
Q: Will this help with maintenance costs?
A: Long-term, yes. STOPFLEX carbon-ceramic rotors are extremely hard and wear-resistant. For most street-driven vehicles, they can last the lifetime of the car, eliminating the need for the frequent rotor replacements common with heavy SUVs using iron brakes.
