Once again saying that a specific suspension has a higher spring rate than another means absolutely NADA, unless they are using the same exact damper. In addition, Solo I can tell from your post that you think very highly of your vehicle and that is wonderful as you should be proud of the vehicle you have purchased through funds obtained from hard work (I assume). However, unfortunately your statement that I have quoted below is incorrect.

First of all, the suspension that comes equipped on the NISMO Edition Z does NOT have the highest spring rates compared to aftermarket suspensions. If anything, the suspension on the NISMO Edition Z is a lot more conservative compared to a lot coilovers that are on the market. I'm going to have to concur with Kwame here; no doubt the NISMO Edition Z surpasses performance capabilities compared to the regular 350Z's but you can easily mod a regular 350Z to outperform the NISMO Edition Z is every aspect of performance. The reinforced chassis does help but the difference isn't phenomenal compared to a normal 350Z.

How am I incorrect when a 350z will never have seam welds on the body/chassis unless they spend a ton of money having it done, it won't have the responsiveness as a NISMO does. My car has been driven by SCCA 350Z owners at Road courses and they all were surprised how well my car did compared to their race prepared 350Z. Don't underestimate the NISMO especially if you never have taken one on the track to it's full potential.

Looks to me like it does other than one in that list. Funny, because like I said, people have driven my car to it's limits on the track, and they have raced prepped cars with roll cages, and my car can shine just as good if not better per them. The suspension is tuned for the car and the body unlike any aftermarket suspension you just slap on it might make it stiffer but doesn't mean it will help the car handle that much better.

Again the body stiffness that was added is very noticeable. You won't notice it on the street but definitely on the track where counts. I also race with the Z clubs in Texas, and on cruises and for some odd reason my car can take the turns about 15-20mph faster seriously than the other 350z with suspension aftermarket mods done to them and my car is stock. They always talk about how I can take turns so much faster than them.

Why would anyone that has a special version of a sports car, that has specific changes done to it to enhance what the car is, install much softer springs just to improve the looks of the car? I mean it toally goes against why you paid extra for the car in the first place.

You cannot purchase lowering springs for the Nismo Z that will drop the car and be equal or better to the oem springs. If you must lower the car, do so with coilovers, one's that actually stand a chance of being better then the oem springs and shocks.

Solo obiviously knows what hes talking about when he owns a Nismo Z. So i would have to agree with him. To me my stock Touring Z performs good for my daily driving in twists and turns.. +1 for SOLO-350Z

Z1 Performance

iTrader: (564)

you don't

it's like asking how do you compare an apple to an orange - both are fruits, but they are completely different in every aspect

Solo is right inasmuch as the NISMO version does have higher spring rates than just about any other SPRING sold on the aftermarket - but that really doesn't mean all that much considering it also has different shocks. The NISMO T2 spec springs (the ones you can buy from NISMO, not the ones that come on the NISMO car) are actually much stiffer than anything else out there I've seen

Anyway, this topic has been beaten to death about a bazillion times already, since before the NISMO Z was available to be purchased. Both are great cars, one is just more evolved from the factory floor than the other. Case closed

NightRider88

could u fill me in as im very curious in this setup?

Z1 Performance

iTrader: (564)

fill you in on the differences between a coilover suspension and a standard NISMO?

other than the fact that you get 4 dampers and 4 springs with each, and they fit on all year Z's, there is nothing at all similar about them

SOLO-350Z

iTrader: (26)

Exactly. That is the one set I mentioned that the NISMO doesn't have higher spring rates over. All that combined with the chassis, makes a nice difference.

Glad this is back on topic. Let's try to keep it this way folks.

NightRider88

let me rephrase that question....will the zeals improve performance? or maybe im just not getting the answer correctly

Z1 Performance

iTrader: (564)

you improve the driver first, then change parts. If you're asking questions like this, in all liklihood you're a novice driver (not saying that in a disparaging way). You would be well served to learn how to drive the car you have, as it's potential will exceed your skill level. When your skill level exceeds the parts on the car, that is the time to change the parts

NightRider88

thats kind of the problem....i dont like pushing my car to the limit continuisly..more room for mistakes...hense why i want to upgrade my suspension...but im not saying theres isnt room for improvement on my part...as there always is room for improvement on the drivers side...

Z1 Performance

iTrader: (564)

what does pushing the car have to do with upgrading the suspension? If you cant currently outdrive the stock components of the car, then don't worry about upgrading it. There would'nt be much of a point

the car is far more capable than you are at this point - when those 2 roles are reversed, that's when you upgrade parts

iTrader: (16)

I agree with Z1 David just wait untill a track day to see if you really need the suspension if all the want is a lower ride height id go with springs. and upgrade your sways would help

iTrader: (13)

IF your not driving the car to the full potential what would raising the potential even more do?

SOLO-350Z

iTrader: (26)

Mainly people do it only for looks and partially for handling. Having more suspension movement will help keep the car a bit more stable over bumps and turns so it doesn't bounce/hop over them like if your car is lowered.

Lowering your car too much can actually have negative effects towards the handling on the car and could cause it to handle worse. You need some movement.

The Zeals will definitely exceed performance over factory Nismo suspension. I am talking direct swap of struts/shocks to coilovers only. If you start upgrading other suspension components, then everything changes.

Like Z1 said, If you can outdrive your Nismo suspension, than go for the upgrade. You're already a better driver than I am, so beat the hell out of your Nismo suspension on track day and if you win, get the Zeals.

NightRider88

thanks for actual good feed back.....which you always seem to have!

Z1 Performance

iTrader: (564)

What I am giving you is actual feedback. Show me another vendor on here that will toss of a $2800 sale because they don't think it's the right thing for you. If you feel the money burning a hole in your pocket, then by all means buy 'em. Why limit yourself to Zeals though? There are units out there that are even more exclusive, and may potentially make the car handle even better. I'm all about selling parts, it's how I put food on the table, but I don't believe in hyping something up just because it sounds cool, unless that is what you want (nothing wrong with that, but that's not the questions you're asking). You said you want to improve the performance of the car. The surefire way to do that, at this point, is to improve you. Once the you part can outdrive the car, then coilovers, among other things, will be a wise and justified purchase.

But to start off, I'd change the tires before anything. The Z, and particularly the NISMO, becomes a completely different animal when on a proper set of r compounds. If you have not done a track day, get in a few under your belt before you just start tossing parts at the car. Learn to critique the car from a position of intelligence and actualities. From there, you'll be in the very good position to describe to any smart vendor, be it myself, or the several others on this forum, what YOU need in a suspension setup. You'll be able to tell them with specifics what is lacking and what you like about the existing, stock setup.
