mustang wheel question

that question has been posted and answered a hundred times, a search should get you the info you need.
i know for the fronts if you dont want to grind down the caliper you will need a spacer. off the top of my head i dont remember the size. for the rear i beleive you just need to swap to gt size rotors.
you can get them from jegs, summit or your local aftermarket rim shop should be able to get a hold of them.
