I Think the low gearset is a BIG plus in a car with 3:23 or 3:55 gears. It will give you the equivalent of a 3.61 or 3.97 gear on launch. For optimal 1/4 mile times you will shift 1-2 a bit higher than 2-3.

You could think of it as a half step to an OD trans with a .80 OD ratio (and the same overall launch ratio).
