All depends what you like. When I built mine it was going to use 10.5Wx31 slicks. I wanted to make the tire look like it was in a stock wheel well. Not jammed to the front and rear edge. As these cars have a larger gap at the rear of the tire than the front. So in my case the front of the wheel well was moved forward 4". The axle was moved forward 3". To be honest I'd like to move them back 1/2"-1". The current wheelbase is 113"
