The R1 Concepts drilled black brake rotor is specified for the front right position on 1977–1978 Buick 98 vehicles. With its drilled braking surface and black finish, it helps vent heat and gases under heavy braking and complements period appearance. Use this rotor when replacing a worn unit, and confirm the year and mounting side to ensure correct fitment.
