    Re: aftermarket LSD's (i need some opinions)

    I was poking around on hybridZ a little. It's just hard organizing information when you don't have an understanding about the subject. Sometimes just asking is best. I think I have a better understanding of the process and things I'll need to do this. I was just unsure of the compatability of aftermarket LSDs with my half-shafts at first. I'm actually looking forward to getting a parts list together! I'm just going to rebuild the broken open-diff. I have with a LSD unit. I just have to decide on which LSD to go with now. I will keep you guys updated (i probably wont start for a bit since I moving soon).

    Anyways, keep the suggestions/info flowing. Lots of good info surfacing here.

    John.

    seems like a good route. i assume nismo units aren't that agressive when compared to the cusco and others? yet a little more on the performance side when compared to a stock CLSD right?

    nismo units have adjustable pre-load.
    one was sold here months ago.

    you remove one axle, put a socket+extension into the splined hole, turn it either direction and change preload almost on the fly, or tighten it up to get some more life out of it between servicing.

    That seems like a really good thing to be able to do; rather than changing out clutches and springs to do the same with other LSDs?

    correct. and they cost roughly the same depending on who you get it from or what kind of vendors you are willing to buy from.

    Yeah, i'm kind of weary about ordering from outside the U.S., but I might have a connection with someone that works at a Nissan dealership. I am going to give him some part numbers and see what he can do. In the meantime I am still looking through forums and searching for vendors.

    Re: aftermarket LSD's (i need some opinions)

    i just read through the differential section of the FSM, holy crap… intimidating work to say the least!

    besides the torque wrench, micrometer and dial indicator, it says you should use some other special tools when completely overhauling the differential. is it absolutely necessary for them? or can one improvise?

    You can still find the nismo ones. They just cost as much as any other aftermarket ones.

    it's been a while, but life has its way of getting in the way of working on my car…
    anyways, just curious if this particular unit will work:

    I've been reading up on that too, but not sure.

    Last I heard Nismo R200 units were out of stock in the US, but would have to check again.

    Not the new GT ones with the socket adjuster like careless said… the old ones like ours (see-through) are hard to find

    Just out of curiosity, does anyone here have firsthand experience driving a Quaife-equipped Z31?
