The R1 Concepts Geo-Carbon drilled-and-slotted rotor is a replacement brake rotor intended for rear-left use on 1994–2004 Ford Mustang models. The drilled-and-slotted face and Geo-Carbon designation identify the rotor style; buyers should confirm side-specific fitment for their Mustang year and pairing needs before ordering to ensure correct installation.
