I'm looking for some new Brake Rotors for my 2007 Z4 3.0i. I have tried searching the forum and have seen a number of posts about BBK upgrade. I am not really interested in switching out the calipers, i just need rotors. Does anyone have any suggestions on brands? I like the look of the EBC drilled and slotted rotors, are they any good? I have seen some bad reviews on Amazon but have seen some good reviews on other sights. since i don't have much experience with this sort of thing was hoping to get some suggestions.
