For me the biggest hurdle was breaking the back end loose and reacting well in that situation. I went a little more extreme, I did a drifitng practice and the PDS 1/2 day thing when you pick up your car. It is important to get that feeling that when the car is getting sideways...you are still in control. I think I take it a little too far and start unncessarily breaking the back end loose. Oversteer? maintain throttle, let the wheel spin and drift. Understeer? MOAR throttle, let the wheel spin and drift. The tire bill gets pretty high.
Back OT...the $3000 price is a deal when you consider the cars you're abusing are not yours and will likely never see them again which means you never have to fix or maintain them. Then the facilities are FIRST rate! Not to mention you're instructors are some of the best PROFESSIONAL drivers around. No offense to HPDE instructors...but the Performance Center guys are a cut above. Lastly, you get the first class corporate BMW treatment!
