That is cool! I have only owned one BMW car, which was a 540i, but my brother in-law here in town had a beautiful 2001 M3. But he moved over to the Porsches. There is a legit track near me in Wilcox called Indie, I think I need to do a track day there. So you are a race car driver?
I did take an SCCA Racing course but never descended into the money pit world of actual SCCA racing. I was an instructor for BMW, Audi, and Porsche track events at Portland International Raceway.
There are lots of car clubs (BMW/Mini, Audi, Porsche, and more) that hold what are called Driver Events on local tracks around the country. All will require you to go out with an instructor to begin with. These are "thou shalt not exchange paint with thy neighbor's car" sessions that let you drive your car in ways that are not possible on the street since there is no cross traffic and passing is in regulated zones only. You get to find out how to really drive your car as it was designed. You have a fun one to play with and would get to find out how well that front deflector works.
