The R1 Concepts Geo-Carbon drilled and slotted rotor is a direct-fit replacement brake rotor for 2004–2008 Acura TL applications, specified for the front left position. The drilled-and-slotted face follows the Geo-Carbon rotor design and this part is offered per corner, so you can replace a single rotor or pair it with the opposite side for matched fitment.
