Hey lucky, did you slap the rotors on straight outta the box? You may want to take them back off and take them to your local machine shop and have them turned on a lathe. That will " true " up any irregularities or runout resulting from being transported from point A to point B It should'nt cost you more than $10 or $20 bucks a rotor depending on what area of the U.S. you're in, notwithstanding Ca. where everything cost a fortune and is taxed to the hilt these days.........where was I ? oh you might get lucky and find a guy who'll do it for a twelve-pack of Bud light, you never know. good luck
