Well you could be right chad, it might be my speakers that add distance to me stopping. But before i had all of it installed, it was still under-par with my gf's car. Plus its not 50lb's its more like 100-125lb's. And im getting tired of cracking windshields and breaking mirrors, so i might sell them anyways

Edit: yeah ill tell you how they work after i put them on Big AL , i should be getting them here shortly. But remember i bought high performace pads too, so that will no doubt have some kind of effect on my braking efforts too. So i wont really know exactly how much the rotors perform by themselves , and wont be able to tell you the real benefits of just the rotors.
