I'm hoping to use Goodyear LSR tires with 10'' x 15" out back and 6" x 15" in front. I've never built a tin top type vehicle or raced one. My experience is in single seaters and I'd like some input from the members on track widths. As she stands right now the widths are the same as measured to the outside of the wheels. I have built in a fair amount of adjustment up front. Any and all help would be great. It's an unequal length "A" arm setup. Thanks.
