The EBC USR Series slotted rotor set for 1979–1983 Ford Mustang 4.2 front applications is a vented, precision-machined British-made rotor engineered from high-quality grey iron. The USR slotted design reduces air noise, helps control fade at speed, keeps pads running smooth and supports cooler braking temperatures—offering a durable upgrade when paired with compatible high-friction pads.
