ok so i ordered a a8bbk and it comes with front rotors. i never thouht of it at teh time but sicne i am doing all my pads and front rotors i might as well repalce my rear rotors. my problem is i might not be able to find the same rotors as i am running in the front. is the a problem or does it not matter if i run diffrent rotors but same pads on teh front and back? thanks

 

people run different rotors, and sometimes completely different brakes in the rear... you will be fine.
