Finally got around to getting some photos - anyone looking for a drop a tit more subtle than swifts and a heck alot cheaper, this may be for you. Mind you this was done on a 35x, but I presume you'd get similar results on a 37x.



Front - 370Z oem front springs, ~1" drop
Rear - G35S oem rear springs, ~.50" drop

Coming from a g37s coupe, the handling still isn't quite as sharp, but it is a night and day improvement over the oem X setup.

Nice to tone down that gap a little, good option for those that need to drive in snow and won't have to worry much about steep drives, speed bumps etc. Like your OEM sport wheels too!

Why didn't you use the g35s front springs?

In terms of height, prokit < swift < 370z < g35s < g35x

I was aiming for something in between, which the 370z fronts did. Unfortunately the 370z rears did not provide the same level of drop.

Oops mine car is a Coupe

How is the spring rate of those springs? My concern would be that the Z holds alot less weight in the front than an X.

From 370z forum:
Regular
F - 7.5kgf/mm (419lbs/inch)
R - 8.1kgf/mm (453lbs/inch)

Nismo
F - 8.6kgf/mm (480lbs/inch)
F - 9.3kgf/mm (520lbs/inch)

Would you happen to know the spring rate of an X?

Swift spring rates for the G37x are 8k front and 7.4k rear

So given the drop in height and rise in spring rate, the Nismo springs would be a good fit up front. Not sure about the drop in the rear though. I'm thinking the S Spring rate might be a bit light in the rear. (for balance)
