The R1 Concepts Geo-Carbon drilled and slotted rotor for 2003–2006 Mitsubishi Lancer, front left, is a vehicle-specific replacement rotor matching the correct mounting and rotor profile for that application. The drilled-and-slotted surface is intended for the front left hub. When servicing, pairing it with the opposite-side rotor maintains consistent wear and braking feel across the front axle.
