Teach me about Final Drive Gears....

^ For AP2 drivers, 4.57 will have the effect that the 4.77 has for AP1 drivers in gears 1-4, and gears 5 and 6 will feel like 4.44 gears in an AP1. Your transmission gearing is shorter than ours so yes, 4.77 will be utterly insane in an AP2.
Steven, you say the extra shift causes you to be in a lower part of the power band "more often" what does "more often" mean? Once? How often do people actually go to an official drag race? I bet 90% of the drivers buying gears have never drag raced in their life. The bottom line is, and there is no dispute here, 4.77 is a quicker gearset than 4.57 (on an AP1) end of story.
If you're a slow shifter than the 4.57 is probably the better gearset, but if you're great and banging the hell out of shifts, the 4.77 is going to put you into supercharger territory. I'm confident that my previous setup could beat a supercharged setup. The trap speed and 1/4 mile times are about the same but in lower gears for street racing I could take a supercharged S with a near stock boost level.
I feel like I keep repeating myself but nobody believes me

Here is the thing I dont understand about the gears and how everyone says 4.77 are the same as stock regarding quarter-mile. Eventhough you do need to shift 1 extra time compared to stock, which in most cases you don't since if you put 245-50-16 in the rear, you would top out at 102 which is the end of 4th gear with 4.77 and usually your quartermile speed, how would stock catch up to 4.77. 4.77 should obtain a big advantage, possibly a couple car lengts with a good shifter. Just because he needs to shift one more time, you would lose all the advantage. So how about in a regular race, not quartermile to 125, the stock will catch up to the 4.77 by 6th gear since the 4.77 needs to shift to 6th before the stock?

4.57s @ 80mphs = about 4500ish rpms if not a little less.
then 4.10s are about 600rpms less then that and the 4.77s are about 300rpms higher then that.
This is all estimated, I'm not sure of the exact formula to calc it

The 4.77 are faster in every single way possible than the 4.57.
The people talking about the extra shift and how it "slows you down so much" don't know how to shift properly. I'm sick of hearing it. I have driven stock, 4.57 and 4.77 gearing. I don't think any of the others saying that 4.77 is slower can say taht. They are going by word of mouth and speculation. 4.77 is faster, and you'll get better times with them, end of story!
At 80mph in 6th gear, 4.77 puts you at about 4900 rpms. Yes, your gas mileage will suck. It'll suck with any gearset. You will be much, much faster though. It puts your car in another league altogether. You no longer have to worry about that pesky 350Z driver next to you. He's now to you what a Prelude was to you at stock gearing.
