OP forgot to say since you are local - if you aren’t already in touch with RRT (Road Racing Technologies) of Dulles, I recommend them highly. They do all my track preparation and know BMWs very well. Your yearly routine should include a track-focused alignment and brake flush (alignment gets knocked out of spec after awhile, so this will prevent strange tire wear from developing).
