The Porsche 911 Carrera S (992) is a precision instrument, but for the owner who pushes the envelope, the factory braking system can become a limiting factor. While adequate for daily use, high-speed emergency braking or sustained spirited driving can reveal the thermal limits of the stock iron setup.
This owner reported a sensation of the brakes "gliding" or lacking bite under extreme load—a sign of brake fade. To solve this and match the car's 443+ horsepower performance, they commissioned a bespoke, no-compromise Big Brake Kit (BBK) featuring Akebono 10-piston calipers and STOPFLEX Carbon-Ceramic Rotors.
The Custom "Hyper-Spec" Upgrade
This build mixes the best hardware available to create a braking system with immense thermal capacity and clamping force, all squeezed inside the 20-inch wheels.
- Vehicle: Porsche 911 Carrera S (992)
- 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 Performance Ceramic Pads
- Hardware: Custom mounting brackets and bolts
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 to pair with this specific high-performance hardware.
Please note: These rotors are custom-configured for the BBK and cannot be directly installed with factory floating calipers or standard factory calipers without the appropriate brackets.
Why This System Solves the Problem
- Eliminating Fade with Thermal Mass: By stepping up to a massive 420mm (16.5 in) front carbon-ceramic rotor, the system gains incredible heat dissipation capabilities. This eliminates the "gliding" sensation caused by overheated iron discs, ensuring consistent, bite-filled stops from high speeds.
- Consistent Friction at the Limit: Unlike steel which can lose friction efficiency as it gets hot, STOPFLEX carbon-ceramic rotors maintain a stable friction coefficient even under extreme stress. This gives the driver unwavering confidence to brake later and harder.
- Refined Aesthetics & Maintenance: Beyond raw performance, this upgrade elevates the car's visual impact. The massive 10-piston calipers fill the wheels perfectly. Additionally, the virtually no-dust pads keep the wheels clean, and the corrosion-proof rotors ensure the system looks brand new for years to come.

Frequently Asked Questions for 911 Owners
Q: Is a 10-piston caliper necessary for a Carrera S?
A: For daily driving, the factory brakes are sufficient. However, for owners who demand consistent performance during high-speed events or track days, the sheer clamping force and pad area of a 10-piston caliper provide an unmatched safety margin and pedal feel that smaller calipers cannot replicate.
Q: Will 420mm rotors fit inside my 20-inch wheels?
A: Yes, but it is a tight fit. This bespoke kit is engineered with compact caliper profiles to maximize rotor size (420mm) while still clearing the barrel of select high-performance 20-inch wheels. It fills the wheel gap completely for an aggressive look.
Q: Can this system be used on the street?
A: Absolutely. While the hardware is race-grade, our pad compound ensures the system remains refined and smooth for street use. You get the performance without the harshness, plus the added benefit of keeping your wheels dust-free.
