All I know is that I don't want to be driving on the track you will be driving on.
Go to a skidpad instead of a track, preferably a wet one so that you don't wreck your car, run into someone, destroy your tires, etc. When you spin your car for the first time, and you will spin your car if you follow some of the advice posted here, a skipad/frozen lake is where you want to be. Contact your local BMW chapter. They should have car control skills courses.
