The R1 Concepts Geo-Carbon drilled and slotted rotor is a direct-fit front left replacement for 2006–2009 Buick Terraza applications. Its drilled and slotted braking surface is designed to support consistent pad engagement and help move debris away from the friction area, offering Terraza owners a direct-fit rotor option intended to improve surface management and dependability compared with plain rotors.
