Nismo Z spring rates revealed
No more guessing, thanks to member T_K who send me the springs to test. We now know the spring rates for the Nismo Z.
Nismo Z (2007-2008) linear front progressive rear
Spring rates 492/336-672
Some interesting facts about the numbers.
Nissan said, the rates were 35% stiffer. Both the front and rear math out to be 57% stiffer vs 04.5+ oem.
Wheel rates: The amount of spring that actually makes it to the wheel to perform work. Spring rate is listed first, then the wheel rate is shown.
2004.5-2008
Front 314= 149
Rear 427= 180
Nismo Z
Front 492= 233
Rear 672= 283
^If you math out the front to rear rate bias, the two setup's have the same rate spread percentage front to rear, about a 22% bias to the rear. Which is not a tuning method I agree with once we start talking about rates that are higher then the oem baseline.
Nissan Motorsports T2 springs
Spring rates 616/672
Wheel rates
616= 292
672= 283
^Notice the rear rate is the same as the peak rate on the Nismo Z.

having a nismo and having upgraded to the hypermax 3 sport, please let me disagree (in regards to the HM 3 sport)
than I can agree on the statement by itself.
it's curious the hypermax 3 sport rates...
F 616

Thanks for the numbers.
All in all the Nismo really doesn't give a much stiffer ride compared to a regular Z IMO. I guess this may be contributed to the progressive rear, improved shocks and added dampers.

Now that I think of it, the ride was much better before I dropped it. And considering that the fronts are shock-body adjustable, it must be because of the rears.
Did you adjust the shock lengths of the rears? I tried it once, couldn't break the collars on the shock free (they were very tight, and the swiveling shock doesn't help), and gave up. Been lazy every since
