The G37X Sedan is the one that most people have the problem with when using the springs for the G35X Sedan.

If you talk with the people at Eibach, they don't recommend using the 35X sedan springs on the 37X sedan. I don't know why they haven't come out with new springs...

Swift has springs that work perfect for this...they had to make a new design for the springs to work on the 37X.

The 09+ G37RWD ATs are a couple hundred pounds heavier than the G35s (due to the 7AT), that's why Eibach and Tanabe have heavier front spring rates for the 37s compared to the 35s. Should be the same for the Xs unless there was some other weight reduction done since 08

Unless it's the rears on the G37X sedan do not have high enough spring rate...?

So specs show the G37X sedan is 87 lbs heavier...so maybe it's the rears from the G35X sedan that aren't right for the G37X sedan? 87 lbs doesn't seem like much though.

Something is definitely different between the springs for the G35X and G37X sedans that does not work and causes the front to sit too high...
