OEM suspension upgrade help- NISMO springs
Hi all-
I've lurked around and seen several threads, but I have two questions unanswered.
I have a 2012 G37x sedan.
1) I've seen stock 370z springs up front work well. Has anyone run 370z NISMO (red) springs? Does anyone have any feedback on running them?
2) I have a 370z rear sway and looking at S sedan rear springs. Would NISMO or standard 370z springs be a good match to these, or would I have a real disconnect in ride quality between the front and rear?
Thanks a lot!

370Z springs experiment - Page 4 - G35Driver
These threads (and aftermarket companies) argue otherwise.
The springs should work. Yes there are differences in other components between RWD and AWD, but the springs should work.

The Nismo springs should be a better choice since the spring rates should be higher (I haven't seen the spring rates listed though). There is quite a bit more weight up front w/ the AWD components so having that higher rate should help w/ that. The fact that Tanabe uses their lowering springs (one part #) for ALL G models will confirm that the springs WILL physically fit in the strut body without issues.

From this thread (what are the oem spring rates? - Nissan 370Z Forum)
Nismo Spring Rates (Rates taken from Nissan Japan, based on part # E3110-1EA00, except for lb/in which was converted from N/mm * 5.7099):
F:79.0 N/mm (8.1 kgf/mm) (451 lbs/in)
R:89.0 N/mm (9.1 kgf/mm) (508 lbs/in)
Normal Spring Rates (Reverse calculated, Nismo was advertised to have 15% more in Front, 10% more in Rear. May not be exactly accurate but close enough)
F: 68.7 N/mm (7.1 kgf/mm) (392 lbs/in)
R: 77.3 N/mm (7.9 kgf/mm) (441 lbs/in)
Of course, that's just what the internet said, I'm not running calculations over here...
I appreciate the offer, I'm just not sure it's a direction I want to go in.

The IPL Coupe springs have a higher rate than any other G37 spring rate and are actually firmer than the Nismo spring specs listed above. I also think the Nismo numbers are reversed. The firmer spring is in front (more weight).
IPL Springs: 549lbs/inch front, 450lbs/inch rear
