hey, i have an 04 at
i am thinking of upgrade my differential to nismo differential, but i can't find much info.
i've been searching around too, but not much description about it.
can someone give me some tip or info about this nismo differential?
thanks in advance

 

Here's a comparision of the various LSD available for the Z. I have the Nismo LSD and I like it. But for some, the chatter from the kicking rubber when turning can be annoying.

It helps you put more power to the ground, when needed.

I'll save you the trouble of research every diff. Your choices I believe are Cusco RS or maybe Nismo with at AT rear diff. Nismo is clunky - not great for a daily driver.

That said, I would (did) upgrade to the 3.5 ring gear (many 6MT owners discard these as they move up) and then pick out either a Quaife if you have an open diff or a ATS/Carbonetics carbon diff if you currently have a VLSD diff (for the sake of install).

These are the top two diffs on the market for our cars.

Contact ForgedPerformance.com - they can help you out.

 

there is also Quaife and 3.7 FD

 

thanks a lot for the info
