APPENDIX A: AUTOMOBILE CLASSES

This is an unofficial transcription of Appendix A of the 2005 SCCA National Solo Rules. (Copyright Sports Car Club of America 2005; all rights reserved;) It is believed to be correct, but any questions should be referred to the official rules as published by the SCCA. Order your own copy here. 

It is SCCA's intention to class all essentially identical vehicles from the same manufacturer (which differ only cosmetically or in nominal marque designation) in the same class. If a version is omitted from the class listing, and is otherwise eligible for the category, then its classification will be the same as the equivalent car which is listed.

All unclassified cars will compete in Super Stock until classified by the SEB, unless covered by a "catch-all" description. To use the catch-alls at the end of the specific car classes in Appendix A, start from Super Stock and work down the classes until a class is found. Such unclassified cars may not be eligible for certain levels of competition (Divisional, National, etc.).  Look for a Tech Bulletin in an early current-year issue of SportsCar magazine for details or call the National office.

For Stock Category vehicles, the vehicle manufacturer's specifications shall be used for specific wheel diameter and maximum rim width specifications.

[Excluded models are listed in the class lists, linked below]
