The EBC USR slotted front rotor set for 1973–1974 Buick Apollo 4.1 applications combines British-made precision machining with a slotted surface to reduce air noise, help control brake fade and keep pads running smooth under demanding use. The USR series is offered as a sport-focused slotted option for improved bite and cooling compared with plain drilled choices.
