Car classing can be a bit daunting, especially for newcomers to the sport. To get started, there is an overview of the major class categories on the Rules/Classes page on this web site.

It is strongly suggested that you download the latest version of the Solo rule book from this page. Start with Appendix A and locate your car’s make and model. Some cars may be listed in more than one class, depending on what modifications have been made. When in doubt, consult Sections 13 through 18 for more detail regarding what modifications are allowed in a particular class. The guideline for interpreting the rules is this: if the rules don’t explicitly state that uou can make a particular modification, you can’t.
