BILL,

Another option is to use light weight 13X6 Steel wheels (Weld, etc) that are selling for $50-80 each (U.S. as I see you're in Canada). They are very light, very cheep, and can be had in a variety of off-sets. And, they clear any brakes you have on the Mustang. Overall diameter of the 13in tire is slightly smaller than the 14in race tire. I was never able to find light, cheep 14in wheels, without going to the money levels of Ron Earp.

I've done it. I believe I got mine thru Summit.

Good racing.

Bill
