Rear gear ratio???

What is the stock gear ratio on these G37's? And is it ever changed out to something different?

I'm talking about the rear differential or "Viscous Limited-Slip Differential (VLSD)". I searched this site and nobody talks about swapping out to a steeper gear set. I think I read 3.69 somewhere but I can't confirm it.

Is changing out the rear gears not done on these cars?

Second ------ 3.193
Third ------- 2.042
Fourth ------ 1.411
Fifth ------- 1.000

Would you like me to simulate a 0-200kph run for you as well?

I hear you there. And I'm asking this because I honestly have no clue, but does the G37 share the same rearend with anything else?

I'm just researching. I don't even have a G37, but the girl that lives with me just picked up herself one. She's in Texas with it now and she'll be bringing it up here later this month. It will stay with me and I've been looking at what we'd like to do to it. Gears are not on the list by the way, but searching this forum I haven't even read where anyone has even mentioned them. I'm way behind on this type of car so I've been reading and searching for the last couple weeks.
I already have a pretty good list started for mods.

I'm trying to get her on here. The mods are going to concentrate on exterior, interior and maybe some suspension. Since it's her car I'll stay away from the drivetrain the best I can. I'll try and talk her into an exhaust though.
