Overview

The Girodisc A1-147 is a 2-piece front floating rotor system designed as a direct replacement for the OE disc on the Chevrolet Corvette C7 Z06 and Grand Sport. No modifications are required for installation, as it bolts directly to the car and works with OE calipers. This upgrade helps maintain factory brake bias and ABS efficiency.

Show original supplier description

The Girodisc A1-147 is a 2-piece front floating rotor system engineered as a direct replacement for the OE brake discs on the Chevrolet Corvette C7 Z06 and Grand Sport models. This system requires no modifications and bolts directly to the vehicle, integrating seamlessly with the factory calipers. By choosing these lightweight, high-performance rotors over a large brake kit, the original brake bias and ABS efficiency are preserved. The central hat section of the Girodisc rotor is constructed from U.S.-sourced 6061-T6 aircraft specification aluminum. The braking surface is made from Girodisc's proprietary cast iron, poured and machined in the USA. These rotors feature a curved vane design, developed for racing applications to function as a centrifugal pump, effectively forcing cooling air through the disc to combat overheating. The rotor and hat assembly utilize a floating mount system, secured by 12 high-strength alloy steel drive pins manufactured by Girodisc. To prevent cold-weather noise, the pins incorporate anti-noise spring washers, allowing the rotor to expand with heat while eliminating rattling. This floating design also enables the rotor to self-center between the brake pads. When it's time for replacement, only the cast iron rotor needs to be changed. This two-piece design, when paired with performance brake pads and high-temperature fluid, offers a robust solution against overheating and warping. The rotors are sold and priced as a pair.
