Well, that didn't work as I has no patience. Temptation was too much after seeing all the rave reviews and thankfully, Nick still had a few left so I took him up and finally got it installed today.

Installation:

A number of people have commented that you need to file/sand a few areas to get the pins on the top and bottom back in. My observation is that you should leave the bottom pin in as you do not need to remove it and will make re-installation that much easier. The part that prevented me from sliding the pin back in the top was that the top hole in the actual spring assembly was a close fit with the pin so I used a round file to take the internal edges off. After losing a circlip after it shot off into the footwell, I went to Autozone and bought a kit of them and had to file one of the kit circlips to get it to fit. Otherwise, it was a pretty straightforward if not physically awkward install haha.

Impressions:

First thing I noticed is that pedal effort was reduced slightly. It does not have that springy over-boosted feel that the stock spring had which is absolutely awesome. There is a noticeable amount of slack at the top of the pedal but I can live with that. The best way I can describe the new feel of the clutch is that it is much more natural. The pedal movement is more linear through the entire range of the clutch's actuation and instantly allowed me to shift more smoothly and consistently in stop and go traffic. It also makes me feel like I can modulate the clutch with much more smoothness than before as the clutch pedal isn't pushing against your foot as much since the stock spring over-boosted the rebound.


Bottom line is this is one of the best mods I have done to the Z to date and for the price and prompt delivery Nick commands, is one of the best bang for the buck drive-ability improvements out there at the moment.
