A1-075 Girodisc 2pc Front Brake Rotors

FITMENT: Ferrari 599 GTB with CCM rotors

The Girodisc system is a direct replacement for the OE disc however a different brake pad with an annulus (pad swept area) of 66mm or less must be used. This is done to keep the rotor weight at a reasonable level. If we manufactured a rotor with the same annulus as the OEM CCM rotors they would be far too heavy.

The necessary pad shape is available from both Pagid and PFC. If there is a specific pad compound you're after, please contact us directly and we'll provide the correct part numbers.

The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from Girodisc's own proprietary cast iron, poured in the USA and machined from start to finish in house. The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.

The rotor and hat have a floating mount system, which utilizes 8 or 10 high-strength alloy steel drive pins, manufactured by Girodisc in the USA to their own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking while maintaining axial and radial float between the hat and disc. The pins are secured by Grade-12 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side, allowing the rotor to grow with heat expansion while eliminating the rattle and noise typically associated with floating rotors. This float also allows the rotor to self-center between the brake pads.

Once the Girodisc system is in place, simply replace the cast iron rotor when needed.
