Girodisc Rear Brake Rotors – Corvette C8
The Girodisc A2-242 Rear Rotor Kit is a direct replacement upgrade for the factory C8 Z51 rear brake discs. Designed to bolt directly to the car without modification, these lightweight high-performance rotors deliver better heat management, improved braking consistency, and reduced unsprung weight—all while maintaining the factory brake bias and ABS performance.
Precision-Built Performance for the C8 Z51
The Girodisc A2-242 system replaces the OEM one-piece rotor with a two-piece floating design that improves cooling and reduces rotational mass. The central hat section is CNC-machined from U.S.-sourced 6061-T6 aircraft-grade aluminum, while the rotor rings are cast from Girodisc’s proprietary high-carbon iron alloy. The curved vane internal geometry acts as a centrifugal air pump to cool the discs during aggressive track driving, preventing fade and extending pad life.
