3.23 Good acceleration, reasonable freeway driving.
3.45 Better burnouts and acceleration, around 3000rpm @100 ie. freeway revs too high.
3.23, 3.45 same as 3 speed, but lower freeway revs.
3.9 - very easy burnouts.
nothing higher the 3.45!!!!!!!
I am very happy with my 3.23 and 5 speed. Probably wouldn’t go 3.45’s In my car.
IMO, 4.11 will slow down your EA.
Remember, higher gears don't always make your car faster, it sometimes does the opposite..
CAUTION: Slippery When BOOSTING!
