Girodisc A1-145 2-Piece Slotted Front Brake Rotor Upgrade, 05-13 Chevrolet Corvette ZR1 C6 Incl Z06/Carbon Edition

Description

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 keeps the rotor weight at a reasonable level. The required pad shape is FMSI 1405, which we can provide in several compounds.

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 proprietary cast iron, poured in the USA and machined entirely in-house at Girodisc. The rotor uses a curved vane design, developed in racing, to act as a centrifugal pump and force cooling air through the disc.

The rotor and hat have a floating mount system, utilizing 12 high-strength alloy steel drive pins, manufactured in the USA and cadmium-plated for long-lasting corrosion resistance. These pins handle braking loads while maintaining axial and radial float between the hat and disc. The pins are secured with class 12.9 cap screws and hardened washers. To prevent noise when cold, the pins are mounted with anti-noise spring washers on the rotor side, allowing thermal expansion while eliminating rattle. This float also enables the rotor to self-center between the pads.

Once the Girodisc system is installed, simply replace the cast iron rotor when needed.
