The R1 Concepts drilled and slotted front left brake rotor in black for 1989–1990 Ford Thunderbird is a replacement rotor that refreshes the contact surface and adds cross-drilled and slotted machining. It helps vent heat and clear pad material during repeated stops, supporting more consistent braking feel under heavier use. Specify it when replacing a worn front left rotor on compatible Thunderbirds.
