i noticed a while back that my rear tires weren't sitting evenly in the rear fenders.i was afraid that my rear end wasnt even. i never noticed it pulling or anything but i didnt want the rear to be road walking. i looked and the rear end measured fine. my mechanic looked and said the after market rear fenders werent even. one was wider than the other. once i got all the support brackets in place the gap between the two arent as noticeable but its lame that you can spend $400 and still get crap like that.
