Hi all, I bought a used 370z a few weeks back. Is there any way to visually inspect the rear diff and tell if I have an LSD versus a standard diff?

Cheers,

Did you buy a sports package? If you did then yes it has VLSD.

lift one side of the rear, put it in neutral and see if it free spins.

What if my foot won't reach the gas pedal while I am holding up the rear end?

Propping up one side of the vehicle and dropping it in gear sounds like a recipe for disaster.

yeah he meant spin it with your hand not the engine I think.

If you have "Brembo style" Nissan brakes, you probably have a "sport package" VLSD (viscous)(which is still crap for anything but DD.)

Lift the ***, put in neutral, spin one wheel, if the other spins in same direction you have a LSD, if it spins in the opposite you have an open diff.

Assuming I don't have an LSD in this thing, what would be a good upgrade diff to put into it?

I'm on my phone so I can't make out your wheel type very well but they look like mine so I'm guessing you have a non-sport model. I also plan on going with an LSD in the future. There are quite a few threads that deal with this subject but one member recently posted that his OS GIKEN LSD (clutch type designed for the 370, not the 350 like Quaife) spent nearly $2,500 in total with all the parts, labor and OSG rear diff fluid as recommended. His review also summed it all up very well. No rebuilding, come in 1, 1.5 and 2 way configurations and super lock. Just need to figure out if you are going to track it, drag it, drift it, or just DD it like me.
