Sorry but your car looks perfect with the combo you already have, and you have answered your own question as 15x7's on the front will make you buy a smaller tire than you already have, you will be lucky if a 195 will fit...
Just tired of looking at Cragars. I've had quite a few cars, most of which had Cragars on them. I would like something different for a change and I have always liked Magnums.
