The R1 Concepts Geo-Carbon drilled and slotted rotor for 2003–2006 Mitsubishi Lancer, rear left, is a vehicle-specific replacement rotor that matches the mounting and rotor profile for the rear left axle. The drilled-and-slotted braking surface is provided for that position. Replace in axle pairs where practical to help preserve even wear and braking balance across the rear wheels.
