To the OP, i suggest checking out the BMW CCA in your area:
http://www.rmcbmwcca.org/
and sign up for one of the car control clinics or driving school events.
You'll get to experience and test how fast you can go when your tail breaks loose as well as other important techniques in a safe and controlled environment.
I did a car control clinic with my DCT and was able to experience whipping the tail around in the skidpad as well as controlling it with DSC off. Plus, you'll have a blast!
