Girodisc A2-147 2-Piece Slotted Rear Brake Rotor Upgrade, 14-19 Chevrolet Corvette Z06/Grand Sport C7 Excl CCM

Description

Upgrade the braking performance of your 2014-2019 Chevrolet Corvette Z06/Grand Sport C7 Excl CCM with Girodisc 2-piece Brake Rotors A2-147.

The Girodisc system is a direct replacement for the OE disc. No modifications are required. The disc bolts directly to the car and works perfectly with OE calipers. By upgrading with lightweight, high-performance rotors instead of a big brake kit, your factory brake bias and ABS efficiency are preserved. The Girodisc rear rotors are approximately 8.1 lbs lighter per rotor compared to stock units (24.7 lbs vs. 16.6 lbs). This significant reduction in rotational and unsprung weight improves acceleration and suspension response.

The central hat section of the rotor is precision-machined from strictly U.S.-sourced 6061-T6 aircraft specification aluminum. The disc is cast from Girodisc’s proprietary cast iron, poured in the USA and fully machined in-house. Each rotor features a curved vane design, developed in racing, which functions as a centrifugal pump to force cooling air through the disc.

The rotor and hat are connected using a floating mount system, which employs 10 high-strength alloy steel drive pins manufactured by Girodisc in the USA to exact specifications. These pins are cadmium-plated for corrosion resistance and secured by class 12.9 cap screws with hardened washers. To prevent cold rattle and noise, the pins are mounted with anti-noise spring washers on the rotor side. This design allows for thermal expansion while keeping the rotor centered between the pads.

Once the Girodisc system is installed, only the cast iron rotor needs to be replaced when worn.
