Front Iron Rotor Conversion for McLaren MP4-12C/570s/650s/675LT by Girodisc
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 unnecessarily heavy.
The necessary pad shape is very common and also found on the Nissan GT-R, Cadillac CTS-V and most AMG Mercedes equipped with 6 piston calipers. If there is a specific pad compound you’re after please contact us directly to provide the correct part numbers.
The rotor and hat have a floating mount system, which utilizes 12 high strength alloy steel drive pins, manufactured by Girodisc to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by class 12.9 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 which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.
Once the Girodisc system is in place, simply replace the cast iron rotor when needed.
When used with performance pads and hi-temp fluid, you have what amounts to a truly amazing solution to overheating or warping rotors.
