Welcome to the home of the Porsche Club of America (PCA) Golden Gate Region (GGR) Points Classification System for the GGR Time Trial (TT) and Autocross (AX) series. PCA members of other regions using the GGR Points System are also welcome to use this site to classify their cars.

Note: If you are driving an unmodified car as normally delivered and specified for use in the United States and Canada, you can use the Zone 7 Showroom Stock classes as described in the Zone 7 autocross rules. Cars that are modified from stock should use this points-based classification system.

In the event of a discrepancy in the class assigned to a car by this site and the class that would be assigned by proper application of the published GGR Rule Book, the published rules will prevail.
