The R1 Concepts slotted black brake rotor for 2003–2010 Chevrolet Cobalt (front left) is an application-specific replacement rotor with a slotted friction surface and black finish. Sized for the front-left mounting location on compatible Cobalt models, it restores a worn braking surface and provides a direct-fit option for brake service or rotor replacement on those model years.
