pulse 9 Report post Posted March 22, 2012 (edited) So I've done some research, and I'm keen to get the Hawk Performance HP Street brake pads for my E85. But looking at their website, something confuses me: http://www.hawkperformance.com/parts/ The 3.0i model has larger rotors (300mm) than the smaller engine versions (286mm). For instance, Hawk only sell rotors for the 3.0i (Part # HUS619). These are the larger versions which would not suit the 2.5i or the 2.0i etc. But when I look up their parts for the pads, they only list one type for the entire Z4 range (Part # HB546F.654) - shouldn't there be two versions to suit the two sizes of rotors? Could I be under-utilising the larger rotor size by using their one-size-fits-all pads? -e- added rotor sizes. I guess 7mm is so tiny, it doesn't really make a difference...
