I have a set of 07 Revised 350Z springs that I would like to put on my 04 Coupe. Since the 350Z springs doesn't drop the rear, would it be ok if I just swap the front springs and keep my rear stock? Thanks.

 

Spring stiffness must be balanced fore and aft to match the body weight. This sets the roll couple stiffness ratio and sets the under, neutral, or oversteer ratios. More importantly these ratios set the critical speed where the body does not pitch up and down on highways with periodic seams or undulations caused by asphalt machine.

Correct ratio, but stiffer than stock raise the tuning speed, obviously 85 mph might be the upward limit as even that degrades 55-65.

 

You always talk to technical Q

I'm not sure if he got his answer in their either...not a direct answer anyways

 

lol yes I'm not that technical. But reading between the lines, I think he's telling me I shouldn't be cheap and I agree.

 

yes, pretty sure the spring rates are the same for those. They are on Canadian vehicles.

 

He's speaking in some kind of code... hmmm
