best rear end for upgrading?

Looking into getting a 370z really soon (next couple of months) and had a question. I want to upgrade the rear to a true limited slip and was wondering what the best route to take was. Can you install an upgrade in an open diff?

I just don't want to be the one-wheel-wonder when taking off quickly....

I've been considering a base model as well. I too want to know what the community recommends.

You could go with the non-sport open diff and get an OS Giken LSD with no modifications needed.

+1 OS Giken FTW. That's my plans.

I will choose J-Lo or Kim Kardashian.

Oh wait, wrong rear end

I bought a base with Touring just for this reason, although I will probably end up with a Quaife although I have also heard nothing but good things about the OS Giken LSD.

You may also want to check out the multiple threads about the 4.08 gears. While you're digging around back there you could shorten the gearing a bit.

Check out Quaife as well.

Also you should just get a 1.5 way LSD.

If you go *BASE* you're sacrificing the big brakes on the SPORT. Here's just a PARTIAL parts cost to upgrade...

Front brake rotor part number: 40206-JL00Ax2 $160
Left front caliper part number: 41001-1EA1B $250
Right front caliper part number: 41011-1EA1B $250
Front brake pads part number: D1060-JL00J $60
Front brake hardware kit (shims & spacers) part number: D1080-JL00A $44
Rear brake rotor part number: 43206-JL00Ax2 $140
Left rear caliper part number: 44011-1EA1A $270
Right rear caliper part number: 44001-1EA1A $270
Rear brake pads part number: D4060-JL00J $60
Rear brake hardware kit part number: D4080-JL00A $43
Brake booster on a SPORT part number: D7210-1ET0A $600

The total is already over $2,100 and thats not the complete parts list or INSTALL cost!

The 2-pin rear final drive flanges are OEM part number: 38220-1NC0A. Others say these work
with OS Giken super locker? I don't see the C-Clip on flanges like the left LSD flange for the SPORT has.
This is based off the OEM parts program diagrams.

Just in case anyone is planning on going from the sport VLSD to an aftermarket LSD and wants to save a little cash, check this out: http://www.the370z.com/parts-sale-pr...port-diff.html =)

Installing it yourself is easy. And free. And all the parts needed can be had for less than $1000.

where are you getting your prices from? I'm looking at upgrading my brakes.... and buying a Quaife lsd.

The Classifieds section here. I got the whole oem BBK package including everything for $800.

What would qualify as easy? Do you have to adjust the gear lashing at all?
