Front spring comparison:
(these are not actual rates, they are a calculation for comparison only)
G35 spring rate = 550lbs
370Z spring rate = 608 lbs
370Z spring is ~ 5/8" - 3/4" shorter than G35 front (sorry for bad tape measure shot)

I hoping to get this pulled together this week.
I pulled the winters & put on the summers just for the base line pics & measurements.
The car is back up on stands with wheels off.
OE struts & springs come off tomorrow night.
& I'll get some comparison data before installing them.
...when you see the thread title change from 'teaser' ....you'll know![Big Grin](https://g35driver.com/forums/images/smilies/biggrin.gif)
^updated with final info

LOL, yep you are right on Wes, I was playing around and wondered who would respond first, I did take it down since you are right, some might think it was the real thing.
