M2/M3/M4 G8X 400mm Front Carbon Ceramic Rotor Set

The Girodisc 400mm 2-piece rotor set is a direct replacement for the factory 400mm front carbon ceramic rotors on G8X M3 / M4 (including CSL / CS) equipped with CCB (gold calipers). These fully floating assemblies reuse the factory calipers and require no modifications beyond swapping rotors and pads. The system utilizes the factory iron pad shape with carbon ceramic calipers. Please get in touch with us if you require pad recommendations.
