Well said!
I recall close to a 100 lbs were saved using the 1LE diff and half shafts over the ZL1 unit.
Additional factors that may hurt the launch is the reduced weight transfer due to stiffer shocks/springs and lowered stance.
The last item I have not researched thus am just guessing, but typically track cars have closer gear spacing between 2nd, 3rd 4th and 5th leaving a tall first gear and big gap to 2nd (not good for the drags with sticky tires, easy to burn clutches and/or bog).
I believe 6th will still be used to knock down the effective final drive using the 3.91 rear to get good mpg.
If any one knows the actual Trans gear ratios that would interest me to compare to ZL1 and SS
