Girodisc Front 2pc 380mm Floating Rotors for Ferrari 430 Challenge Girodisc

The Girodisc system is a 380mm direct replacement for the OE disc to allow the use of 18″ wheel/tire packages. The only modification necessary is to swap out the factory shouldered caliper studs for the 430 road car spec brake caliper bolts, lowering the caliper to allow the use of a 380mm rotor.

The central hat section of the disc is made from 6061-T6 aircraft specification aluminum.  The disc is made from cast iron, constructed in the USA and is made 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.

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 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 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 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.
