The R1 Concepts Geo-Carbon drilled and slotted brake rotor fits the rear left of 1991–2001 BMW 850Ci models. The drilled-and-slotted face and Geo-Carbon finish noted in the product name support heat management and pad debris evacuation during everyday use. This position-specific rotor is intended to replace a worn unit and restore a true braking surface for consistent rear brake response.
