To determine what changes move cars between V, S, P, I and M classes see the complete PCA classing rules. The complete PCA classing rules can be found in the 2019 PCA Parade Competition Rules:  2019 Parade Competition Rules 1st Edition. Autocross rules are on pages 16-30. The section on Event Size Classing is missing. We use a modified version of the Small Region classifications that were last published in the Parade Competition rules from 2017 on page 28. Please note: There was no Parade Competition Rules for 2020 and the 2021 one will not available until later this spring.

Porsche Classes
Oregon Region PCA Autocross runs under a modified version of the small region rules. Be sure to check the allowed modifications section in the Parade Competition Rules (see link above) if you have made ANY changes (including R tires or larger tire sizes) to your stock vehicle. The intent of the Showroom Stock class (S01, S02, S03, & S04) is to create a class for automobiles as normally delivered and specified for use in the United States and Canada. Factory options as normally delivered for a specific model year are permitted. However, anything beyond this, especially anything that could be reasonably perceived as being performance affecting would not be allowed in Showroom Stock. For example, Automobiles must run with their spare tire, jack, lug wrench, owner’s manual(s), tools, etc. Cars running out of class will not receive Championship Points. If you have questions contact your Autocross Chairman prior to the event at: Autocross Chair
