The R1 Concepts Geo-Carbon drilled-and-slotted brake rotor is a direct replacement for the rear left brake on 2004–2012 Chevrolet Cobalt models. Its drilled-and-slotted face and Geo-Carbon construction provide a consistent friction surface and help evacuate water and debris at the pad interface. Designed as a direct-fit rotor, it matches the listed years and wheel position for straightforward installation.
