Well it's time to do something about the brakes on my 2007 Mustang GT. The car has 46k on it and the brakes are going out (I moderately abused them.) I have 18" Bullitts from the factory and am not really interested in going with a different wheel/tire combo at this point. What size/brand rotors and pad would I be able to go to without having to go to a big brake kit ? Are the powerslot rotors any good? How about the stoptech kit from Brenspeed? Eradispeeds? Do drilled rotors vs slotted rotors crack and last less time?
