OSGiken LSD purchase questions!

dP3NGU1N

So after scouring the forums for about 2 hours and doing my part to try to figure things out on my own I haven't come to any certain conclusions so I'm hoping people will help out and chime in.

I want the OSGiken LSD, I found the part number I need which is OS NS111-HA. Same LSD as the 350z MT.

I have a 2013 base sport 370z (stock vlsd) and there are mixed responses on serveral issues. Now some of the other threads that I read up on had such erratic responses that I didn't always know which question was being answered so I ask that anyone providing answers please number it according to question. For the sake of my sanity...

1. Does a sport model 370z need extra parts to install the LSD?

2. If so, What other parts are required? Can they be ordered directly from Nissan (part numbers?)

I got very confused with this because some people said yes, some said no, some websites (z-1 performance) said yes and they had a package, some websites (forgedperf) didn't say anything at all.

3. What is the price if not MSRP ($1600 roughly)?

I ask this question because I read a thread (also regarding the OSG LSD) where a lot of people thought that $1600 was apparently rather high and that it must have been MSRP price. Well so far as I know unless you've got the hookup people generally pay MSRP price for parts. Perhaps someone who has purchased the LSD can tell me what they paid up front, not including install.

Also if any vendors would PM me their best prices that would be awesome. Otherwise I'll be reaching out privately to some of the vendors that helped out the other threads that I've read.

These are my major concerns. If more arise during the course of this thread I will append it to this post.

Thanks for reading.
