The R1 Concepts Geo-Carbon drilled and slotted brake rotor fits the front left of 1988–1991 BMW M3 models. The drilled-and-slotted face and Geo-Carbon surface noted in the product name provide a braking surface that helps manage heat and channel pad debris during normal road use. Ideal when replacing a worn rotor, it restores a true contact surface to maintain consistent pedal feel and stopping behavior.
