The Girodisc system is a direct replacement for the OE disc on all vehicles that came equipped with cast iron rotors from the factory. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is made from cast iron to the same specification and material as used by professional racing organizations. It is a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.
Features
- The rotor and hat have a floating mount system, which utilizes 10 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
