Why do discriminating Porsche owners choose to upgrade to a STOPFLEX Carbon-Ceramic Brake System? It stems from an uncompromising pursuit of performance. While the Panamera 971 is an engineering marvel, its substantial weight and speed can push standard brakes to their limit.
This case study features a discerning owner who wasn't satisfied with standard solutions. They commissioned a bespoke braking system pairing the massive clamping power of Akebono 10-piston front calipers with the reliability of Brembo 4-piston rear calipers, all anchored by STOPFLEX carbon-ceramic rotors.
The Bespoke Upgrade Plan
This build features a custom "best-of-breed" configuration, utilizing different top-tier caliper brands for the front and rear axles to achieve specific performance goals, all fitting within the 21-inch wheels.
- Vehicle: Porsche Panamera (971)
- 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 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
- Massive Clamping Force & Stability: The 10-piston Akebono front caliper distributes pressure evenly across the massive 420mm (16.5 in) rotor. This setup provides immense initial bite and modulation, essential for stopping a heavy Panamera from triple-digit speeds repeatedly without fade.
- Transformative Weight Reduction: STOPFLEX carbon-ceramic discs are over 50% lighter than comparable steel rotors. Reducing unsprung mass by this magnitude sharpens the Panamera's turn-in, improves suspension compliance, and makes the large sedan feel significantly more agile.
- Refined Performance: Despite the race-grade hardware, the system is designed for street usability. The pads provide excellent cold bite and smooth operation. Additionally, the virtually no-dust formulation keeps the intricate wheels clean, preserving the car's premium aesthetic.

Frequently Asked Questions
Q: Why combine Akebono and Brembo calipers?
A: This is a bespoke configuration designed to maximize performance on each axle. The 10-piston Akebono front caliper offers immense clamping force for the heavy front end, while the Brembo rear caliper provides reliable, balanced performance for the rear. It's about using the best tool for the job.
Q: Is this system reliable for daily driving?
A: Absolutely. While the hardware is race-derived, the system is engineered for refined street performance. The pads are formulated to provide smooth engagement and consistent stopping power in all weather conditions, not just on the track.
Q: Will this fit my 20-inch wheels?
A: This specific configuration with 420mm front rotors generally requires 21-inch wheels for adequate barrel clearance. However, we offer other rotor sizes (such as 405mm or 410mm) that can be tailored to fit certain 20-inch wheel setups. Please contact us for fitment verification.
