i bought new rotors from
http://www.nolimitmotorsport.com/prod/FS00042 and i thought they were front rotors. they are sold 10.4 mm rotors, the guy helping me change my brakes said they wont fit up front because they are to small... the old front rotors are vented and much wider.. my question is can i use these in the front (with stock calipers) or did they send me the wrong brakes?
