I have an 05 sedan with Sports suspension.
My question is, can i just swap out my springs and put in unrevised 350z springs and i should be ok? Also, i read that the unrevised suspension is really bouncy on the 350z ... if i keep my g35 sport shocks and just use the 350z springs, i wont get that bounciness will i?

 

You will be fine w/ that swap.. Ive seen alot of sport sedans use the unrevised.. ask one of them..

 

It isn't the springs, it's the shocks that caused the bounce problem. You'll be fine.

 

ok thats good,
im thinkin about buying some used unrevised 350z springs. They have 30,000 miles on it already, but my car is around 30,000 miles too. Will buying used springs with 30,000 miles on it be bad? Also, how much would you pay for it.
