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?

G37Sam

There you go shumby:

Gear -------- Ratio (:1)
First ------- 4.923
Second ------ 3.193
Third ------- 2.042
Fourth ------ 1.411
Fifth ------- 1.000
Sixth ------- 0.862
Reverse ----- 0.771

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

G37Sam

Yes the final drive axle ratio for the 5AT is 3.69:1 IVoidWarranties

Are there aftermarket gear sets out there?

G37Sam

I havent seen anything on this forum yet but give it sometime
vendors are still having troubles coming up with a proper intake (which is a pipe and filter lol) for our cars

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?

G37Sam

ok here's the question
What are you trying to do exactly?

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.

G37Sam

oh yeah i saw your thread..i knew your username rang a bell..
wow a girl with a G37 and wants to mod.. if i were you I'd marry her lol
whats the mod list so far lets see it

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.

G37Sam

yeah forget about messing with the drivetrain.. she will def. need an exhaust! stock sucks right?
