Thanks for the replies. I'll check around for more club options. I just found this:
COMMA - Hallett Motor Racing Circuit and it looks like a great option (to work up to). PCA is probably going to be my best bet for learning and collaboration. I just need to make the time available. I'm looking forward to
Oktoberfast at Hallett, even if I don't drive the track. Looking forward to meeting Woody and other mid-USA forum members.
Tires... I've seen enough posts, that I just have to do my homework. I really need to wear out a current set of 17s so I can get some good new ones.
I think the Audi swap is going to happen, but not in a hurry. The current 2.5L engine in my S gets it down the road, but would be an embarrassment in any sort of competition....
