i want to get my rims widened to 10 inches. what places can do this for me? how expensive is it? i was thinking of doing this to my wheels but someone told me that you have to have spacers on the mustang to make the 17x10 work. would it be safe to run spacers on my car. i have hit the 11's and dont want my wheel falling off. also where do i get the spacers from? i am just trying to get my wheels setup and i am toatally lost as what to do.
