The R1 Concepts Geo-Carbon drilled and slotted brake rotor fits the front left of 1991–2006 BMW 328i models. The drilled-and-slotted face and Geo-Carbon finish named in the product identity help manage heat and channel pad debris during normal driving. Use this position-specific rotor when replacing a worn unit to restore an even braking surface and preserve consistent pedal behavior.
