Hey my friend has a 350z track and he just took replaced his springs... Will puting his used springs on my sport sedan improve anything are they the same springs ???

 

Need more info....

what year is your car? do you have the sports suspension on your car? There should be a drop (not positive what it is) but the rates may or may not be different IIRC.

 

it is an 03.5 with sport suspension..

 

They will lower your sedan 1". However, what year of Z did they come off of?

 

it's an 03 350z

 

03 oem Z springs have the same spring rates as the oem springs that sedan's with the sport suspension. You'll benefit from the 1" lowered center of gravity. The sedan's oem sport suspension shocks won't mind the springs, but it goes without saying that Tokico D-specs would improve things a lot.
