I just purchased a big brake kit for my 04 with Alcon front calipers and 13 inch rear rotors with new ford rear calipers. I haven't tried to mount the rears yet but I get the feeling I'm going to need to get new brackets to mount the calipers out further to accommodate the New larger rear rotors. I was hoping someone could fill me in before I open up my brake system and make my car imobil. Do I need brackets and if so where do I get them? Thank you much!
