hi fellas, got myself a 2007 350z gt with already installed tien lowering springs, how do the stock springs feel? im planning on raising if it isn't too much different so i can install a veilside v3 kit. id search it but it is pretty specific through brand so i figured why not?

so... how is the roll feel? i take some sharpish turns and hairpins at 40 without much roll if it provides a bit of details. im still new to the mod world

 

imho: any full bodykit will look cool and function how it should only with air suspension. Other way it is a compromise: you have a cool looking static car, or tractor-high drivable car.

 

Ok so... How's the feel of stock suspension?

 

Stock suspension was designed by great ingeneers, overall its not bad compared to other vehicles, though it has some weak sides...

 

Like what? Should I just raise the front a bit? Or does that inch or so look funny?

Any recommendations for similar Heights besides air?

 

'07 Z has the revised suspension over early Z33, which has a horrific bounce/jarring motion to it. Newer suspension is much more compliant (new shock valving and spring rates) so, it has a reasonably good ride for a Sports/GT. Firm but not uncomfortable as Nissan would sell zero cars to the masses who buy the car for mere transport while looking aesthetically pleasing if the ride were bad. That'd be the majority of new buyers back then.

Your Tein springs probably ride stiffer and provide less roll than a stock Z (if you are referring to "roll" in the "lean over" sense (vs "roll center change"). HOWEVER, unless you specify which particular Tein springs you have, it's hard to actually give a sense of the delta between OEM and aftermarket springs.

Tein S-Tech or H-Tech.... S-Tech is firmer/has higher spring rate. H-Tech is a lowering spring but with nearly the same spring rate as OEM. So, no one can tell you how much difference there will be without knowing for certain which ones you have.

I'm failing to understand why you would want to raise the car to fit a body kit.... the whole premise of a body kit is to make the car look good and all swoopy like (for want of a better word, laff...). Generally, people who are putting on such a kit want it to be low for that extra "cool factor".

 

So it's drivable but with similar clearance. And s-tech is the type. So how much softer would the stock be? Massively noticeable?

 

Stock Spring Rates F/R: 314/427

vs.

Tein S-Tech F/R: 386/402

So yes, it would be noticeable. But you don't mention type of shocks nor condition of same. If OEM, they're probably going to ride close to the same with a slight difference in stiffness "feel".

If aftermarket shocks, it will depend on type. Shocks are the biggest determining factor in the ride quality - given similar spring rates - as they are what control the spring movement.

Shocks from a comfort/ride quality perspective (best to worst): Bilstein, Tokico Blues, OEM, Koni (set at lowest setting), almost any coilover (set at medium jounce/rebound....softest settings still worse than stock, GENERALLY speaking).

Bottom line is there are too many variables (shock type, quality/age of same, combination of springs/shocks, etc.) for anyone to give you a definitive virtual answer. Suffice that to improve your suspension's ride, look at shocks first THEN springs.

 

Ok, I'll simple it down then, as far as seller told me, only thing changed was the springs because the oem Springs rusted out, which means they were replacement, which also means the shocks are oem

 

It feels like stock suspenssion

 

Sweet, any good places to find the oem Springs? Or similar ones? It's hard to find on Google, I keep getting forum stuff and old for sale stuff

 

Look in private classifieds here on my350z - there are a couple of oem suspension part-outs

 

Tein S-Tech springs don’t lower the car very much. It’s only 0.7” front and 0.6” rear.

If you want stock height, you can install Tein H-Tech springs.

The S-Tech springs will probably work better with a body kit.

 

If you decide you want to go through with going back to stock, I have some stock springs that I'm looking to get rid of. Shoot me a message if you're interested.

 

Unless your driving a 98 taurus its highly unlikely that oem springs rusted out. Actually dont think ive ever seen them do anything but bust in half on saab's and fords

 

I took the Tein springs my 03 came with off, replaced with stock springs and shocks. I haven't noticed any bouncing, the ride is slightly softer (which is fine with me as we have a pothole breeding program here) and handling on the public road is not appreciably different. Still slides the back out like a dream. It's about an inch taller which helps a lot as I don't scrape the bottom anymore.


If you replace the springs, do the shocks and shock mounts too. And get it aligned after.

 

I live up by the mountains and I'm pretty concerned that a v3 veilside front bumper would hump the ground on beat up roads. That's what worries me, but I still like stiffness. But if my car hasn't come close to a bottom out yet....

 

Speed bumps made some roads inaccessible before I changed.

 

I think some of em hit my side skirts

 

Interested in stock OEM springs for the 350? They ride well, minimal body roll, but were designed greatly by Nissan. I have some used springs from my 2008 z I could sell you
