you said you were lowered 2.75 inches? i dont see how this is possible looking at your picture. there is still some small fender gap left in yours and mine is only lowered 1.75 and its lower than that in this picture of mine. not that it matters thats just my observation. but for the wear, as was said, check your toe-in, that will shred a tire in a couple of weeks if it is off http://www.geocities.com/blue2gnt
