and in case you cared:

1st = 3.321
2nd = 1.902
3rd = 1.308
4th = 1.000
5th = .759

final = 4.083:1

autos are different (except for final drive), but I don't have them memorized...

SR 5th is .838 :D

I memorized them because I was doing the calcs so much to figure out what diff and tires to get and all that.

ehhh I was close lol! man as much as I love that 4.36 most times, it wasnt until the road trip to new orleans that I really hated it. this unit may end up in our project car for a stint and I may get another LSD for my S14 pumpkin. back to the 4.08, unless going to a 17x8 is gonna help things. its late and I cant think which way I'd need to go to offset that a little.......

go with the biggest diameter wheel/tire combo you can fit to even out the lower final drive gearing. however, if the point was getting quicker acceleration, that sorta defeats the purpose. I want the 3.916 gears from an Infiniti J30.

welll I didnt exactly buy them they came with my diff. so I wasnt expecting to get it. I'd almost run 17x9 if I could get them all around. I dont wanna run a staggered setup. I may try and squeeze the 9s up front and go like that with a 45series on it. ehh we'll see
