Start with the official SoloII rules. The 'rules', as it were, are listed for saftey, what class your car would be in by type, year, and modifications. A good place to freshen your knowledge on the basics.

Someone have the 2007 link handy? Additionally, some Auto-X clubs may use variations or other rules, etc. (either less or more restrictive). I've got my last 2006 link for national, but not sure if any changes were made yet.
