Anyone Have Before & After Results of 4.30+ Gear Swap
Like the title says, anyone have any real 1/4 mile results for comparrison of the steeper gear swap. Some say it may do more than a lot of other bolt-ons combined, but no one has any real numbers that I've seen.

......and i went and tossed in a JDM / Altezza 4:10 LSD ... if you thought the car was geared low before ... hehehehehe... going from,.... what is it?.. 3:90 for a OEM US 5 speed ? IIRC, the US got one or the other dep on 5speed or auto tranny...either 3:70 or 3:90 ...
doesnt sound like much but 3:70 or 3:90 to 4:10 made a big difference..

Well lots of guys have swapped in the 4.30's and said that it wasn't much of a drop in mpg overall and it only looses a little speed off the very top end, but that it made a significant difference in the car's speed.

Just thought I'd post some relevant calculations with stock manual gearbox and different rear end ratios:
W55
3.73 FD / W55 / 6500RPM shifts
Gear---MPH-----KPH
1st-----36-------58
2nd-----63------101
3rd------94------151
4th-----130------209
5th-----153------246
3.91 FD / W55 / 6500RPM shifts
Gear---MPH-----KPH
1st-----35-------56
2nd-----60------97
3rd------89------143
4th-----124------200
5th-----146------235
4.3 FD / W55 / 6500RPM shifts
Gear---MPH-----KPH
1st-----32-------52
2nd-----55------89
3rd------81------130
4th-----113------182
5th-----132------213
