2021 and newer BMW M2, M3 and M4 (G8X), rear axle, 370mm. As replacement rings, these require serviceable existing hats and hardware. Confirm your rear rotor diameter and hat condition before ordering.
Installation notes
Brake work is done by axle rather than by corner, so both sides wear evenly and the vehicle tracks straight under braking. Clean and lubricate the caliper slides and hardware while everything is apart, inspect the hoses, pistons and dust boots at the same time, and follow your vehicle's service manual for all fastener tightening. Bed the new friction surfaces in gently before any hard or repeated heavy braking, then allow a few hundred miles of normal driving for the pedal to settle before judging feel.
