These guys know a whole lot of nothing.They half way ruined a pair of rotors and told me they were warped to much run out they are beyond the point of cutting them, after they already tried cutting them and jacked them up and of course offered to sell me theirs for $200. I asked if they measured the rotors...there reply NO.Went down the street to another parts store they fixed it no problem,plenty of life left. O'reillys has no real knowledge if its not in there computer they have no clue.STAY AWAY!
