These GiroDisc 2-piece rotors are a direct replacement for the rear 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 48 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 rotors (part number D2-282) 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. The hat is made from 6061-T6 aluminum and coated in a black anodised finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and Belleville washers for race-ready float while also being street-friendly with no noise from loose hardware.

The minimum thickness at which we recommend replacing these rotors is 22mm.
We also recommend replacing them if a crack leads to the edge of the rotor.
 
 
CARBON CERAMIC DISC OPTION
These GiroDisc 2-piece rotors are a direct replacement for the 400mm carbon ceramic front rotors on the BMW G8X M3 & M4.
The 2-piece, fully floating assemblies utilise 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.
