GIRODISC FRONT ROTOR RING REPLACEMENT - C8 CORVETTE Z51

GiroDisc Front Ring Replacement  Replace your rings on your Girodisc 2pc Rotors for your C8 Corvette. Rings come complete with all new hardware and instructions for re-assembly.  The disc is made from proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. 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 12 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 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. Simply replace the cast iron rotor when needed.
