Nismo VS Sport Package Springs, Struts and Shocks

kenchan

the only thing the base z really needs imho is a tad stiffer front swaybar and grippier tires as far as handling goes.

ValidusVentus

Yeah I believe you are correct when you said they only make them for coilovers, never seen one with the proper ID to fit the stock spring seats. Unfortunately.

There's a lot of douche-baggery and misinformation in this thread.

First. Swift Spec-R spring are indeed progressive. Swift Springs USA

Their metric coil over springs are not.Swift Springs USA

"Spec-R" is a product. Swift makes a Spec-R for a lot of different vehicles. The Spec-R for the 370 is not the same as the Spec-R for any other vehicle.

That being said, OP. Do not go to the Nismo suspension. Don't waste your money. Figure out what you are going to do with the car first and then put a budget together. Suspension is expensive, and you get what you pay for. The more you pay, the better it gets.

If you are on OEM suspension, the best bang for buck you can get is a new front sway bar. Buy a Stillen, set the front full stiff and the rear full soft. The next best upgrade would be either a 1-way coilover+springs, or if you don't want to learn about springs then just buy Koni yellows + the Swift Spec-R springs. You won't be disappointed with any of the above. The nismo dampers and springs are nothing special.

Meh still need grippier tires per my post.

victorofhavoc

i agree, the best upgrade to improve braking, handling, acceleration, cornering, and overall grip, is to improve the only thing touching the ground from the vehicle.

I agree too. But you still have to keep the tires on the ground.

and Dont forget to include a good alignment set up with the equation!

Thanks to all for their input, this is a great informational thread!

I purchased a set of nismo shocks and springs and have the swift springs on their way right now.
I daily my car and occasional autox so want it to handle better yet with DD comfort still in mind.
I will post what my opinion is on these when i get them installed. probably in a week or so.

From what i have read i agree this is probably not going to be the best track/autox setup but if its a upgrade ill be happy, Specially for the price since i got a great deal on the nismo set.

Coming from an HR 350Z, the 370Z feels soft and floaty (40th Anniversary aka Sport/Touring)

I heard the Nismos feels like a 350Z - I loved how that car handled, My favorite by far.

So i installed the nismo shocks with the Swift springs this afternoon.
Installation:
Pretty straight forward no issues.
Picture of the difference from nismo shocks with springs and with the swift ones:

Quick tip on compressing springs:lol they dug into the ground and stayed quite in place.



Initial Impressions:
-They feel stiffer in a way that after bumps and imperfections in the road the suspension settles faster. I don't know if i can say it feels more comfortable until driven harder its just different. I like it though.

*im not going to get an alignment for a week to let the suspension settle so initial impressions might change*

Turn in is most definitely improved. Much more feedback at turn in and if front is settled it stays that way and sticks through the corner.
The rear is more loose and the back end slides out easier than before at low/medium speeds. Im guessing this is due to the increased negative camber more than the springs, at longer faster corners it feels more planted. Like i said these are initial impressions so most likely going to change.

As far as the drop I noticed it as soon as i left my driveway the plastic piece under the bumper scraped the driveway. That piece is not going to last long im sure.
These pictures are in a incline so the front looks higher than it is. i will post better pictures tomorrow.



This really makes me want to get spacers. Ive heard 15mm up front and 20mm in back is ideal right?

Ill drive it for a couple of days and post again with further impressions and pictures after it settles and from the rear to show the new negative camber.

Thanks

FWIW I have a '14 Nismo and replaced the springs with Swift's, then went to coil overs. I like the stock Nismo springs better than the Swifts. While stiff I found them more responsive and predictable and less mushy than the Swifts. The coil overs are far and away a better ride if you're looking for performance - it's really no comparison.

Don't waste your time installing the Nismo springs on your car. It was bone jarringly stiff and terrible. I'm sure it's great on the race track though! When I installed them on my base/sports it raised my front .5" to 28" (wheel arch to ground, was 27.5 before). I went with Swifts and have been extremely happy with them. They are softer when driving around town, but really stiffen up when you drive hard. You can see why in the coil design. The close coils for comfort, and the larger gap for performance. I wouldn't discount them for street/track use they are a great spring.

It's a pickle, yes it is. Swifts or coil overs????? If you price Koni yellows and swifts you can put 1000 or so with it and score some quality coil overs. HKS, Bilstein, or KWv3's. They are not top of the line but better than the knock off arama's.
