The EBC USR Super Silent slotted rear rotors for 2003–2006 BMW Z4 3.0 are precision-machined in the UK from high-quality grey iron. The narrow-slot USR pattern reduces air noise while helping brakes run cooler and resist fade at speed. These vented rear rotors measure 294mm diameter and 19mm thick with five bolt holes, offering a premium slotted option for rear replacement.
