The R1 Concepts drilled and slotted brake rotor for 2004–2010 Chevrolet Optra (U.S. and Canadian models), front left, is a black-finished rotor that renews the pad contact surface. It features drilled holes and machined slots and serves as a replacement for a worn rotor at that wheel position; inspect rotor mounting and pads when performing brake service.
