I was a SCCA member but let my membership drop when my regional comp lic expired because I couldn't get the required races in in one season. I am trying to get into autocross now and it looks like the SCCA might be the best show in town. I'm thinking of joining up again for autocross events(in Western Ma) and to work the ALMS race at Lime Rock.

Check out this forum "Trackpedia" . A lot of these guys race and a number of them have Porsche's. Trackpedia Discussion Forums - Powered by vBulletin I'll bet they can answer the SCCA being Porsche friendly questions, seems to me I heard rumors they weren't.
