The R1 Concepts Geo-Carbon drilled-and-slotted rotor for the front right of 2009–2016 BMW Z4 is a vehicle-specific braking part intended to match that wheel position. Its drilled and slotted face with Geo-Carbon treatment aids heat dispersal and pad surface cleanliness to support consistent braking feel.
