Okay, I'm really new here. I'm talking as of five minutes ago. My dad has a 2003 that he wants to do some work to. We are already looking at intake and suspension and making a list of other things he wants to do. One of those is he wants to put wider tires on it. He agrees with some people that the stock wheels look like golf cart tires. He wants to have a better wheel base but does not want to compromise the performance. Does anyone know what the wheel well dimensions are so we can know how wide we can go without taking out any of his turning radius? Its for a 2003 Cooper base. Any help would be greatly appreciated.
