GiroDisc 2021+ BMW M2/M3/M4 (G8X Excl CCM) Slotted Front Rotors

These GiroDisc 2-piece rotors are a direct replacement for the front rotors on the G80 M3, G82/83 M4, and G87 M2 without carbon ceramic brakes. Our 2-piece, fully floating assemblies help shed unsprung weight and rotating mass from the front axle of the vehicle. 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 D1-282) when they need to be replaced. All major components including the hats, rotor rings, and drive pins are manufactured in-house at our facility in Bellingham, WA from domestically sourced materials.

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