I installed a set of S-TECH springs a 8 months ago. I noticed that the back end was starting to sag a bit more than usual so I was looking to find a few different suspension options. I found a guy that was selling the suspension off his 350z for a great price so I figured it couldn't hurt to try the setup. I finished installing the rear but I haven't done the front yet. I also installed a set of adjustable camber arms as well as toe arms in the rear to prevent bad tire wear.

So this is the setup I have now:
Front: S-Tech Springs / Stock Struts
Rear: 350z Springs / 350z Struts / ADJ Camber Arms / ADJ Toe Arms

I drive a windy mountain road to work everyday and I noticed right after the change that the rear end really wanted to spin. I came around a lot faster but way to fast. It feels the same as when you put a really stiff sway bar on a front wheel driver but looser. I checked the spring rates on the tech page and I'm really curious to get some imput if the strut is valved and different (stiffer or softer) from the 350z in the rear and any opinions on the combination that would be most ideal to run. If it was what I had on there (stock struts & S-Tech) then I'll just switch back, but if anyone has a better idea as to a better combo with what I have now, the information would be appreciated.

Should I go ahead and do the front conversion to the 350z Struts and springs? Switch something around? I just want to get it setup nice until I can get my coilovers in a few weeks.

I've been driving FWD cars since I was young so switching to the RWD platform has definitely been a learning experience over the past year.

Thanks again ahead of time.

 

Your car looks great. Does your car have an adjustable sway bar? If it does, what setting is it on?

 

No the sway bars are stock right now. Any info?

 

Switch out the Stechs in the front for the Z spring/strut, it'll sit a little higher, but we've all had good experiences with full Z suspensions on the sedan.

looks great, i would do full 350z suspension. I am actually getting it and my friend has it on his 03.5 its a perfect drop. For sway bar i would go with Stillen or Hotchkis bars, also nice wheels 19s HP Evo rims?

 

Ok I'm going to swap it out tomorrow to see if it fixes the problem. I'll repost and let you know. I also had a chance to purchase a set of Standard coilovers for a really good price, any of you guys ever heard of them?

 

is the brand actually called "Standard"??? If so, no, i've never heard of them. Post up a link.

Here is the picture of them & they're 24 position valve. They guy and his wife have them on ebay but they live really close so I called them and talked to the guy for a few. They have a coupe that they race and they have them on their car and the guy said they did really well on the track and that they have a ton of adjustments. They have 10 sets and said they would sell me one for really cheap. Any info could be helpfull.

I finished the installation of the 350z setup and the car "rides a bit stiffer" but feels softer in aggressive cornering. I think this is what people refer to when they say that springs are linear and progressive. The car feels really good on longer rounded corners but on the quick stuff (posted 15-25mph corners) it tends to feel a lot softer, especially when there is a series of them in a row. I think I might swap the front springs with the S-Techs I have to see if that makes a difference.

 

When you installed the rear Z springs, did you get it all realigned? I think if you raise the rear with diff springs (Z), the camber/toe settings might negatively affect the handling.
