Which Diff?

It is a great, informative post... but one thing i disagree with is that you have to run carbonetics gear oil on their diff. That is just a ploy to sell their overpriced gear oil. We're running motul of the same viscosity and works great. I've talked to a number of folks in the know that think this is fine.

That may well be - but I know when we have asked them, as well as the former importer of them, both said that only a couple of fluids were deemed "ok" by the factory - one was their own, the other was by Neo and I don't think was even offered in the US. I even had asked about Motul, since we use it alot, and was told "we don't know". Doesn't mean other stuff can't be used, just what they told me. Their new fluid is reasonably priced ($50 for a gallon, I always have it on the shelf, as well as Motul and OS Giken's fluids) it's just the short change intervals with the carbon based diffs that stinks

Yeah, we're planning to change mine pretty much every other track weekend. That plus you really should run a diff cooler with these, which with install can cost just as much or more than the diff itself

Was convinced by my girl to just keep the OS Giken and not worry about the money and get it installed because she knew I wanted it real bad. LOVE IT. Like Z1 stated with the open diff, Night and Day difference and I'm completely in love with it and SUPER stoked that I got the OS Giken. Worth the money and I don't get any of that clicking or grabbing that the one guy was saying with his, obviously bad, Nismo diff. Anyone thinking of getting this should, there really isn't any intrusiveness but definitely a noticeable difference in traction and where the power is being put. LOVE IT, thanks Z1.

I'm glad i didn't steer you away from buying it

. I think my problem is the ether the install or the type of Diff oil.

On a side note: After driving the car on a track day, things started to quiet down.

As i said this is my first LSD so I'm not really qualified to answer questions.

+1 Good choice - The OS Giken unit is great. Just got to make sure to have the necessary install components for the 370Z! I recommend installing the Nismo diff cover at the same time since there is no additional labor.

I just got my diff rebuilt with Cusco 1.5RS, 4.08 gears and mounted with Whiteline bushes. Am running it in at present.
