The R1 Concepts Geo-Carbon drilled-and-slotted brake rotor is a direct-fit replacement for the front left position on Cadillac CTS models (2003–2008). It carries the drilled-and-slotted Geo-Carbon surface specified for that wheel location and is offered as a vehicle-specific rotor to match the factory pattern when replacing a worn rotor or refreshing the braking assembly with like-for-like components.
