Let me just start out by saying that the Z31parts.com Poly Diff Mount is an excellently constructed piece...incredibly well packaged and beautifully assembled. Install was fairly easy as I had access to a lift...took under an hour from start to finish.
I noticed the difference IMMEDIATELY upon clutch engagement, like as soon as I backed it out of the garage bay...believe it or not, shifts are now FAR smoother with my ACT 6-puck.
That was just the beginning. I have always had a slight clunk from the diff that I always assumed normal from the ACT racing clutch. GONE.
On power cornering traction has also been very noticeably enhanced, and breakaway seems to be far more linear than before.
All in all i am absolutely thrilled with how well this product has performed in my short testing session. I highly recommend this product to anyone...especially those with an LSD unit.
Something else that was kind of strange I though I might mention...as some of you may know, my car was manufactured in 1/87 so it did not come with a stock LSD, however, the first or second (Most likely second owner) swapped in an R200 LSD from a later car...come to find out the top of the diff mount has a hand written stock number as well as "89 300ZX Turbo" written on it! Just thought it was a neat little discovery and I thought I would share. Pretty neat seeing as there were only 210 '89 Turbos made for the states, and I have one of the diffs!
