In the world of 600+ horsepower sports cars, braking isn't just about stopping; it's about control. This modified Porsche 911 Carrera S (992) produces supercar levels of thrust, but the owner found the braking experience at V-Max speeds to be "gliding"—lacking the initial bite and rock-solid pedal feel required for confidence. The solution was a no-compromise, bespoke braking system: Akebono 10-Piston Calipers paired with massive StopFlex Carbon-Ceramic rotors.
The Struggle
When you double the horsepower of a car, the stock brakes often become the limiting factor:
- "Gliding" Sensation: At very high speeds (250+ km/h), standard iron brakes can lose initial bite as heat builds instantly, creating a terrifying feeling that the car isn't slowing down fast enough.
- Thermal Saturation: Repeated high-speed braking events saturate iron rotors quickly, leading to a soft pedal and reduced confidence.
- Unsprung Weight: Heavy iron rotors dull the sharp, telepathic steering that the 911 is famous for.
Technical Specification
This is a complete Custom Big Brake Kit (BBK) overhaul. It replaces the factory calipers with a mix of top-tier OEM suppliers (Akebono/Brembo) and pairs them with massive StopFlex Carbon-Ceramic rotors, fitting perfectly within 20-inch wheels.
| Vehicle | Porsche 911 Carrera S (992) |
|---|---|
| Front Hardware | Akebono 10-Piston Caliper + 420mm CCB |
| Rear Hardware | Brembo 4-Piston Caliper + 410mm CCB |
| Weight Saving | ≈ 24 kg (53 lbs) Total Reduction |
| Pad Material | StopFlex Low-Dust Ceramic Compound |
Compatibility Redline
This is a Custom Big Brake Kit (BBK) application. It upgrades the front axle to the massive Akebono 10-piston fixed calipers and the rear to Brembo 4-piston calipers. This system requires 20-inch wheels minimum for clearance.
Engineering Validation
1. Eliminating the "Glide"
The 10-piston Akebono caliper provides a massive increase in pad surface area and clamping force distribution. Combined with the 420mm (16.5 in) StopFlex rotor, this system delivers immediate, linear bite even at triple-digit speeds. The sensation of "gliding" over the disc is replaced by the feeling of hitting a wall of deceleration.
2. Infinite Thermal Headroom
With a rotor capable of withstanding temperatures over 1,300°C, this system is virtually fade-proof. Whether you are attacking a canyon road or braking from V-Max on the Autobahn, the pedal feel remains rock-solid and consistent, stop after stop.
3. Sharper, Lighter Steering
StopFlex carbon-ceramic discs are over 45% lighter than comparable iron rotors. Removing approx. 24 kg of unsprung mass sharpens the 992's already brilliant turn-in response, making the front end feel even more eager and precise.
4. Visual Dominance
The massive 10-piston front caliper and 420mm rotor fill the 20-inch wheel barrel completely. This "full" look signals the car's extreme performance capability and sets it apart from a standard Carrera.

In-Depth 992 FAQ
Q: Why use a 10-piston caliper on a 911?
While 6-piston calipers are standard for high performance, a 10-piston setup offers the ultimate in clamping force distribution and pad surface area. For a tuned car with 600+ HP, this ensures that braking power is never the limiting factor, providing a massive safety margin.
Q: Why mix Akebono front and Brembo rear calipers?
This bespoke configuration allows us to select the best-performing component for each axle's specific needs. The Akebono front caliper offers immense power for the heavy braking load (70-80%), while the Brembo rear caliper provides reliable balance and integration.
Q: Will these fit under my 20-inch wheels?
Yes. This specific 420mm/410mm rotor package with these calipers is engineered to fit within most high-performance 20-inch wheels, filling the barrel completely for a purposeful, race-ready look.
Q: Does this eliminate brake dust?
Yes. The ceramic pad compound produces virtually zero dust. This is a massive improvement over the standard pads, keeping your wheels clean and protecting the finish.
Q: What is the lifespan of these rotors?
For a street-driven 911, StopFlex long-fiber rotors are effectively a "lifetime" component. They resist wear and oxidation far better than iron, eliminating the need for frequent and expensive rotor replacements.
