GiroDisc 2-Piece 400mm Slotted Front Rotors - BMW M3 / M4 (G8X, carbon ceramics)

These GiroDisc 2-piece rotors are a direct replacement for the 400mm carbon ceramic front rotors on the BMW G8X M3 & M4. Our 2-piece, fully floating assemblies utilize the factory calipers and require no modifications other than switching the rotors and pads. These rotors use the factory iron pad shape with the carbon ceramic calipers. Please contact us if you need help finding pads. The rotor rings are machined from a proprietary casting made of high-carbon iron formulated to GiroDisc’s specifications. This superior metallurgy results in a rotor that holds up better, and the 72 curved vanes act as a centrifugal pump pulling air in through the hub to effectively cool the rotors under hard use. The 2-piece design means a reusable hat which can be attached to new rings (part number D1-220) when they need to be replaced.

Fits: BMW S58: M3 (G80/G81), M4 (G82/G83), M2 (G87). Confirm your exact car with us before ordering.
