T-bone, my point is on the track you can easily downshift the SMG twice from a high speed straight to a tight corner. However I'm pretty sure the current SMG can do 2 gear down shifts by quickly hitting the downshift paddle twice. I've only driven a SMG on the track at Watkins Glen which is a 3rd and 4th gear track. 2nd and 5th gear aren't used, at least in my dad's stock 2002 SMG M3. 140mph on the backstretch though, how much fun is that?
Swamp, I can see the need for downshifting on the highway for a quick getaway, however I was talking about track use where you're either full throttle or full brake for 90% of the laps.
Enigma - your description is exactly what I was talking about.
