Just got back Friday night from Alanta Motor Speedway where my son (37 years old) and I attended the Lexus Performance Driving Academy course I have to agree with everything that SpeedFreak said. We were able to ride with a professional driver around the course for a couple of laps and he really hung it out.
My wife has a new BMW 335i conv with the selectronic automatic with paddle shift. There is no comparison with the ISF's tranny. I have not driven the dual clutch automatic of the M3 so I can't really compare. I think that the problem you had on the track was not knowing the correct gear you wanted to be in as you approached the exit of the turn. After a while driving you will almost automatically downshift entering the turn the same way you would with a 6 speed, sequentially down the gears, until you reach the one you want exiting.
My son has a 330ci and recommended that my wife get the 100k BMW warantee. He said she would need it. Sounds like he was right.
