Yea...I'm trying to keep the car as narrow as posible. The rears will be interesting to fit. I'm currently looking for a 13X8 or 13X9 to test fit in the rear with a 225 tire. I'm more concerned with the width of the car in the rear since it's usually a little closer to the cones than the front tires.
There's someone on sccaforums selling a set of 13x10s for $200. Get 'em now!
