Does anyone know of a company that widens (aluminum) wheels? I am looking at a set for my 4th gen Camaro, and they only go up to 17x9.5, which is fine for the front, but I would really like 17x11s in the back. If anyone knows of a company that does this, or has had any experience with this (positive or negative) please let me know. Also, if you have any idea on pricing, that would be cool, too. Thanks alot!
