SCCA ProSolo and Solo2 Autox classing can be excessively confusing for the un-indoctrinated.

The SCCA Solo2 Rule book is a cluster of rules that attempt to properly categorize each vehicle into “fair” classes. We wont be going into detail on how well they are doing this. This will simply explain the current Class organization structure and basic legalities of each class in regards to the Subaru Impreza. This will also apply to other vehicles but there maybe some minor discrepancies, any questions can be emailed/commented to me or brought up on any of the many National and Local SCCA forums.

There are different “base” classes.

Street
Street Prepared
Street Touring
Street Modified
Modified
Prepared

There is some overlap in the classes about what is legal and what isn’t so it is important to understand the class structure before getting too deep in the modification process.
