GiroDisc 2 Piece Slotted Front Rotors - C5 Corvette / C6 Corvette
These rotors are a direct replacement for C6 Corvettes with the Z51 package. For all other C5 and C6 Corvettes, you will need to upgrade your brake caliper abutment brackets to accommodate the larger rotors. You can do so by using GM parts #88964166 (front, x2) and #88964167 (rear, x2). No other modifications are necessary. The disc will bolt directly to the car and work with OE calipers perfectly.
The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our own 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 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.
