The R1 Concepts slotted black brake rotor fits Cadillac CTS models from 2003–2008 and is listed for the front left position. The catalog notes a slotted braking surface and a black finish, making this a matched replacement option for the front-left rotor across those years. Confirm year and wheel side to ensure proper fitment before purchase.
