The R1 Concepts Geo-Carbon drilled-and-slotted rotor is a replacement brake rotor for Buick Rainier (2002–2009), specified for the front left position. The rotor’s drilled and slotted design helps keep the pad contact area clear and supports consistent braking response. Supplied as a single rotor for the listed wheel position, it is intended as a direct replacement when front rotors are being changed.
