The R1 Concepts Geo-Carbon drilled-and-slotted brake rotor is a direct-fit replacement for the rear right position on Cadillac STS models (2004–2011). It carries the drilled-and-slotted Geo-Carbon surface specified for that wheel and is intended as the vehicle-specific rotor choice when replacing a worn unit or matching the original drilled-and-slotted configuration during brake maintenance.
