When your Corvette’s braking performance starts to fade, the Girodisc D2-324 Rear Replacement Rings are the solution. Designed for the Corvette C5 and C6 Z51, these high-performance iron rings restore the incredible stopping power and thermal control that Girodisc systems are known for. Whether you’re tearing down a straightaway or cruising through canyon roads, this replacement set keeps your braking system fresh, balanced, and ready for action.
Each ring is crafted from Girodisc’s proprietary high-carbon cast iron alloy, poured and machined entirely in the USA. The design utilizes curved internal vanes that act like miniature air pumps, constantly pulling cooling air through the rotor faces to minimize heat buildup and reduce brake fade. If your original Girodisc rotors have reached their wear limit, these direct replacements will bring your system back to peak performance without the cost of new hats.
