I have an '01 TT, and just got a new set of wheels and tires so I can get into autocross. I will probably be going to Qualcomm for just about all events, but I was wondering if anyone had tips on what organization to do it through. I know that Porsche Club of America and the SCCA San Diego are pretty big, but I was wondering what the costs are for membership fees and to go to events for different organizations, and which would be the most recommended.
