The R1 Concepts Geo-Carbon drilled-and-slotted brake rotor is a direct-fit replacement for the rear left position on Cadillac CTS models (2003–2011). It features the drilled-and-slotted Geo-Carbon surface specified for that wheel location and is supplied as the appropriate vehicle-specific rotor when replacing a worn unit or matching existing drilled-and-slotted hardware during brake service.
