Hi Guys,
I'm new here, as I just purchased a 1985 CRX SI for Solo 2.
Being from Western Canada, my club uses the Western Canadian Motor Association (WCMA) rules. Our rules and classes are slightly different than the SCCA rules. We have a class between Stock and Street Prepared, called Super Stock, that allows mainly allows constrained handling mods and minor power mods. In trying to compete in this class, I am trying to follow the tire/wheel guidelines, which summarized states that:

When viewed from directly above the fender opening, perpendicular to the ground, no portion of the tread at the top of the tire , may be visible…basically, the tires should not protrude past the fenders.

I obviously want to put as much down as much tire (R compounds) as possible, while staying within the rules and using a 13” wheel.

Any suggestions on lightweight wheel / tire combinations that can do this. I wanted to go 13 x 7, but have concerns that this will lead to tire protrusion.

I have searched quite a bit for a solution on the net, but can’t find much info, because of our localized rules.

Thanks in advance.

David
