Patrick, I don't know anything about the Solo rules at all. What are you required to run for belts? The best bet would probably to pull up a copy of the rules from the SCCA site, and go from there.
Sorry I can't be of more assistance, but the road racing rules are a whole different ball game from Solo.
Matt Herd, from the forum, Solos a 1500 Midget. See if you can give him a bump for some advice.
