STi Regional Forums are on the way. You should be able to find plenty of people and plenty of racing in your area through this website after that. You might even find some Club STi meets. 8)
Until then check out: http://www.scca.org/
for SCCA sanctioned track times and so forth. Warning they have a big website, or maybe a lot of smaller regional websites all lumped into one, is a better description.
It took me a while to find the So. Cal. area racing, but persistance paid off in my case. I hope it does in yours as well. I have also called them and found them to be helpful over the phone.
