Or go with the Carbonetic or OS Giken that uses the stock shafts.

Good to know - thanks.

For aftermarket, the best choices to consider are Carbonetic, and OS Giken, IMHO. There are others, but these two have the best performance and are least intrusive from a sound/grabbiness standpoint.

I am looking forward to trying out the OSG, since it doesn't require the very frequent fluid chances as needed by the Carbonetic diff. Might also be interesting to try the Carbonetic Metal diff, vs. the carbon diff that is popular.

Yep... too bad Nissan only offers a base ,sport package instead of having the customer spec the Z! Likely Zs would come without radios, limited diffs, better/wider tires/wheels, springs/shocks/sways, BBK,etc.

I just purchased an LSD for my Base model Z. Does anyone know where I can get output shafts so I can install the LSD? Is there anything else I will need?

There is one LSD in particular that is designed for the Base that includes everything. You will have to talk to your vendor to see if they can source the shafts for you.

I have about 2500 miles on my OS Giken and I'm loving it. In ax the car hooks up like you can't believe. Pretty much goes unnoticed on the street with exception of real slow parking lot speeds doing sharp turns. It occasionally clicks when doing slow tight turns.

It depends a lot on how you drive the car. I drive mine extremely hard on twisties in the mountains, but I am not driving like on a race track where it's full brakes into the corner and full power out, for me the challenge and fun is carrying corner speed, not full g's into or out of the corner. In between the corners (if there is any) I am enjoying the view. At the limit of cornering force, you'd be hitting the traction control with more than neutral throttle anyway (and I would never do TC off on tricky unpredictable mountain roads, often damp and with moss). So I would not ever likely spin up in inside wheel. Also doesn't our car brake the inside wheel if it spins anyway? Have fun you maniacs.

Boy this thread got brought back. But I'm going tomorrow to Forged to get my OS Giken installed. Boy I can't wait from all the things I've read. I've never owned a car with a more than sub-par LSD. Now with my suspension, brakes, and now this I'll be set for the twisties and track.

Let us know how you like it. I'm looking to upgrade my open diff, and having a hard time deciding what would be best for me.

I'm defiantly going to have a review. I'm so tired of a open diff. That's all I had on my 350 and it was FI also. Stupid mistake.I've learned some hard lessons from wreaking my last one.

But from my search the OSG is the way to go in every way. I'm also getting a tune tomorrow. I hope some more than average things can come from this.

Good luck with the install. Let us know how it goes and how it feels.

I'm just curious, why do you think it's the clear choice over a Quaife? Especially now that the Quaife's are under a grand shipped.. it's hard to justify anything else for myself since it's a daily and I don't track my car much.
