I know that they fit and i know that it will work. Anyone here have this setup?

G35 S-Tech: 1.2" front, .9" rear, 358 lbs front (6.4 kg) and 274 lbs rear (4.9 kg)
350z S-Tech: .7" front and .6" rear 386 lbs front (6.9 kg's) and 403 lbs rear (7.2 kg's)

Seems like the G35 S-tech will offer a better drop without the need of the spring mount mod.

Post pics if you got them~!

 

G35 coupe and 350Z oem ride heights are different by about .5" so any spring that drops the Gcoupe a given amount, drops the Z that much less if you install it . And please take a look at the rear spring rate that G35 setup uses,.........way too soft. The 350Z S-tech is a much better choice.
