I bought these for the gorgeous extra bling they give my car at first, and they certainly do that, but they also are great street rotors too! I just got done bedding in the pads & they are perfect now...no hint of warpage or pulsation in the pedal at all. I get a very good bite on them with stock OEM Bullitt/Cobra pads this sure looks to be a good investment for my 94GT Roush Clone! Not very many miles on them yet but all good so far! Love 'em!
