A1-145 Girodisc Two-Piece Front Brake Rotors

FITMENT: Chevy Corvette Z06/Z07 (C7), Front w/ OEM CCM

Iron Rotor Conversion

The A1-145 Girodisc system is a two-piece steel rotor and aluminum hat combination that directly replaces the fragile and expensive front ceramic brake rotors on the C7 Corvette Z06 with the Z07 package¹. Upgrading your brakes with these lightweight, high-performance replacements is an excellent solution to the expensive, fragile ceramic rotors on the C7 Corvette Z06 w/Z07 package.

The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron constructed in the USA, made to the same specification with the same material used by professional racing organizations. The rotors' curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc.

The rotor and hat mount together through a floating mount system which utilizes ten high strength alloy steel drive pins manufactured by Girodisc in the USA to their own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by Grade-12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors.

The two-piece Girodisc design allows for disc-only replacement as well, minimizing future replacement costs and delivering outstanding performance.

Sold/priced per pair.

¹ Note: These Girodisc rotors have a different annulus (pad swept area) than the OEM CCM rotors, to maintain their light weight. A brake pad with an annulus of 66mm or less must be used with these Girodisc rotors. We recommend using the Cobalt C7 Z07 racing brake pads with this system.
