I have always loved the big tire look on a Cobra or other '60s sports car. This picture of Grants old boxster gives me wood.
He was using phone dials and cantilever slicks as a cheap autocross setup. I would love to do this. Only problem is I don't think I could replicate the look with normal street legal tires. I'm sure there would be a significant performance loss going from 17" to 15" on street tires also. Is there such a thing as cantilever street tires that would give back some of the performance to wide tire on narrow wheel?
