Show original supplier description
The GiroDisc A2-324 is a high-performance, direct-replacement rear rotor set for Corvette C5 and C6 Z51 models. The slotted design improves heat dissipation and reduces brake fade, ensuring consistent braking performance under rigorous conditions. The rotors are constructed from GiroDisc's unique cast iron and feature a U.S.-sourced 6061-T6 aluminum center hat. This two-piece design significantly reduces rotational and unsprung weight compared to stock rotors (11lbs vs. 18lbs), which contributes to improved acceleration and suspension response. The internal cooling is enhanced by a racing-inspired curved vane design that drives cooled air across the disc. The assembly utilizes high-strength steel driving pins manufactured in the USA and cadmium-coated for corrosion resistance. Anti-noise spring washers are included to prevent rattling and noise when the rotors are cold, allowing for proper thermal expansion while eliminating typical floating rotor noise. These rotors are sold and priced per pair.
