so i was wondering how much would the 350z H&R sport springs 1.3f and 1.0 R drop on a g35?

 

This topic has been beat to death, a simple search would yield your answers.
Add about .5" for a coupe and 1" for sedans.

Read thoroughly.

 

you can google g35 350z hr pic or something like that and come up with pictures of almost any setup, that is what I did when I was deciding on my springs..

the z aftermarket springs can lower a g pretty low, but the spring rates tend to be better (at least for what I wanted) than similar ones offer for the G's (a lot of G springs were too soft)

but like 4D05G35 mentioned there are hundreds of threas on this
