The EBC BSD rear rotors for 2003–2006 BMW Z4 3.0 feature a V-slot pattern that disperses heat and helps pads run cooler than OE-style discs. These sport rotors combine high-carbon, thermally stable construction with a silent slot design to improve braking feel and add visual appeal. They are vented, 294mm diameter and 19mm thick with five bolt holes for direct rear replacement.
