I have up for grabs is a set of rear springs for a 350z made by Hotchkiss. These springs will fit G35 sedans and coupes.

$60 shipped
email me at Clyons0203@yahoo.com
Specs are:
Springs rate rear - 330lbs
Drop rear - 19mm (on a 350Z) drop will be more on Gcoupe, and even more on Gsedan)

will trade for an revup air box (with big velocity stack) or HR y-pipe

 

These springs will give you the lowest drop on stock shocks. Best springs for the G35 sedan!!
