Unleashing the Beast: The AMG GT 63 S Carbon-Ceramic Brake Conversion
The Mercedes-AMG GT 63 S is the apex predator of the super sedan world. With a 639-horsepower bi-turbo V8 and S-Class levels of luxury, it's a machine built for crossing continents at incredible speed. But harnessing that monumental power requires a braking system of equal caliber. While the factory iron brakes are capable, they represent a compromise—a final shackle on a car that begs to be unleashed. This owner opted for the definitive solution: a full STOPFLEX Carbon-Ceramic rotor conversion.
The Upgrade Plan: A Targeted Evolution
The goal was to give the GT 63 S the thermal endurance and reduced weight needed to match its incredible engine. This was achieved by retaining the powerful factory AMG calipers and swapping the iron rotors for our advanced carbon-ceramic discs.
Front Axle: The factory steel discs were replaced with our STOPFLEX 420mm (16.5 in) Carbon-Ceramic Discs.
Rear Axle: The rear steel discs were replaced with our STOPFLEX 360mm (14.2 in) Carbon-Ceramic Discs.
Brake Pads: The system was completed with a full set of STOPFLEX Performance Pads, designed for the AMG calipers and carbon-ceramic surfaces.
Why This is the Essential GT 63 S Upgrade
For a car with the mass and velocity of the GT 63 S, managing heat is everything. This conversion is the single most effective upgrade for any owner who drives their car with intent.
Thermal Dominance: A two-ton car moving at speed generates immense heat under braking. Our carbon-ceramic system's ability to absorb and dissipate this heat without fading is its single greatest advantage, providing a crucial margin of safety and performance.
Synergy with AMG Hardware: Our rotors are a direct bolt-on replacement for the factory discs, engineered to work in perfect harmony with the powerful OEM AMG 6-piston calipers. This unleashes the full potential of the exceptional hardware that already came with the car.
The Result: Power and Control in Perfect Harmony
This conversion fundamentally enhances the GT 63 S, making it a more capable, confident, and rewarding car to drive, both at the limit and in daily use.
Absolute, Fade-Proof Stopping Power. The car can now be driven as intended—hard and fast—with the complete confidence that the brakes will deliver brutal, consistent stopping power every single time. Brake fade is simply eliminated from the equation, whether on a racetrack or a demanding mountain road.
A More Agile Super Sedan. The significant reduction in unsprung and rotational mass makes the big GT 63 S feel lighter on its feet. The suspension can better control the wheels, sharpening steering response and making the car feel more athletic and willing to change direction. It's a palpable improvement in the car's dynamic character.
The Finishing Touch of Luxury. The upgrade delivers on refinement. The iconic yellow AMG calipers now frame a high-tech carbon-ceramic rotor, creating a true supercar aesthetic. Furthermore, the virtual elimination of brake dust keeps the beautiful 21-inch wheels looking pristine, preserving the car's menacing, upscale look.

Questions About the GT 63 S Upgrade
Q: Mercedes offers a factory carbon-ceramic option (PCCB). How does this compare?
A: Our system provides a comparable, and in some cases superior, level of performance by using the latest-generation carbon-ceramic composite materials. For owners whose cars were not equipped with the expensive factory option, our kit offers a path to achieve that top-tier performance as a direct, bolt-on upgrade, utilizing their vehicle's existing powerful AMG calipers.
Q: Is this upgrade necessary for a car that is mostly street-driven?
A: For a vehicle with the immense power and weight of the GT 63 S, having a massive thermal safety margin is a huge benefit even on the street. It provides unparalleled confidence in emergency braking situations. Furthermore, the benefits of improved handling from reduced unsprung weight and the virtual elimination of brake dust are appreciated every single day.
