Hey everyone, I want to put the RS*R springs made for the 350z on my G35 coupe, because the drop is minimal and what i need. However, how safe or reasonable is it to put the RS*R's on my G35? any help would be appreciated.
Here are the spring rates for any reference that might help me also

The coupe can use any Z lowering spring*. I think your choice is better than going with the eibach's for the coupe, which have a very low initial spring rate. Who know's maybe the RSR's do to, but I highly doubt that. In short I think it would be a great idea.

(*Whereas a sedan owner MUST add a additional amount to the published drop for that given spring ment for the Z or coupe, around a additional 7/8" front and 1 1/8" rear. Being that your coupe starts off with springs that are the same height as the Z's springs, you don't have that issue).

I believe that RSR is coming out with a G35 version soon. It say TBA on their website. I think .6 drop is perfect since I don't want to spend the money for a camber kit and won't cause that many problems.
