The A2-145 Girodisc system is an upgrade to a two-piece steel rotor and aluminum hat combination as a direct replacement for the C7 Z07's rear carbon-ceramic brake discs. The Girodisc system bolts right up and work flawlessly with the stock rear calipers and parking brake system. We recommend using the Raybestos ST43 or Pagid 2487 racing brake pads with these Girodisc rotors.
Upgrading your brakes with these lightweight, high-performance replacements is an excellent solution to the expensive, fragile ceramic brakes 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 in the US from cast iron, made to the same specification with the same material used by professional racing organizations. The rotor's curved-vane design was developed in racing as a centrifugal pump to force cooling air through the disc.
The rotor and hat mount together through a floating mount system of high strength alloy steel drive pins, manufactured by Girodisc in the US to their own specifications and 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 rotor only replacement as well to minimize future replacement costs and deliver outstanding performance.
