The reason I think the gearing will benefit- Quicker offline stomp Especially with TOD (this is why the WRX-STI kills off the line). 40 mph in 1st gear with stock gearing is way too high for launching. over the last half of the track you are in 3rd - being lower would accelerate a little better. Our trannies have "racing gears. Closer ratio for track style- not drag racing from a stop to 1/4 mile. No one else in the world does this hence no import has good drag strip gearing. around maybe once off the line, and then keep racing between say 30 to 110 mph. Another option would be to use a smaller diameter tire than needed for looks for a trial run. Like a 16" rim w/ wide performance car tires maybe 25" total diameter. This would equate to lower gearing. If someone could try it I would guarantee lower times.
The Trooper has identical gears although the old late '80's Trooper 2 boxy style had a wide tire option w/ 4.77 gears. Hard to find, and not compatible to our larger late model trooper components. Our front axle is the back of an old boxy trooper hence you can get a limited slip from an old trooper rear and put it in our front.
