Nismo VS Sport Package Springs, Struts and Shocks

carlitos_370z

hahahahahaha!!!! good to you buddy well if this make you feel better i track my car too... like i said... everyone have their opinion.... the reason that i mention that my Z is for daily commute is cause for me the springs are very capable for track use and have the comfort to drive every day...

Im not putting a handgun in the head to anyone... and say hey buy Swift springs or i shoot you.... Im giving my review of something that i install in my Z and of course i take the time to do a research before make the decision to buy it...

I respect your opinion... and I hope you respect mine

If you dont like them... its simple dont install them... what you said are not going to change my mind on my review

Have a nice day dude!!! i hope i dont hurt your feelings

victorofhavoc

My feelings aren't hurt man. What you choose to do with your car and how you see it are definitely your opinion and up to you.

I just want the OP to have an informed understanding of modification choices since suspension intricacies can be a very complicated thing. There's a lot that goes into it besides a spring.

Happy Friday, and have a good weekend!

You are obviously making assumption that the Swift springs are progressive and they are not. You're making statements without the fact and experience.

There are many people here have Swift springs and like them.

'Performance' is very subjective, but if you are referring to pure tracking duty, I doubt that any after-market springs with stock shocks are good enough. You probably have to spent tons of cash and replace most of the suspension components and 'TUNE' it according to the type of track.

All of the after market springs such as Swift is for those who want improvements over the OEM's with fairly low cost and Swift is one of the better one for that purpose.

I think if you can grab the nismo springs and dampers as a package for around 500 bucks and then pair them with adjustable anti roll bars it will be money well spent. Yes you can pick up cheap 3000000 way adjustable damping "coilover" kits for a little over 1k but who knows what the adjusters truly do and you likely don't need them anyway. Koni yellows are not a bad option but I personally couldn't tell you what range of spring they were designed to dampen. Perhaps Koni will , and you can pair them up accordingly. And just to clear up a debate here. Swift makes both progressive (Type R) springs as well as linear (Swift Race Springs) for the 370. You can tell them apart visually with a glance.

You can get a lot of grip out of the 370z stock setup. I've had the OEM dampers put on a shock dyno and tested. They have good characteristics. They might not be the stiffest and best feeling, but they are great for their purpose, make grip on bumpy roads while keeping the driver a bit comfortable.

Yeah I don't support any aftermarket spring without proper dampening for any racing/performance driving whatsoever. Experience I have plenty of, and I've seen the swift springs everyone has (type r) in person and they are definitely progressive.

Edit: meant that most people have, not everyone.

Read the post below:

I agree with you there. For 4-500 that would be a solid deal.

I thought the swift race springs were standard fit for 3 different coilover sizes only? Do they make a linear spring that fits the stock suspension? have a link by chance?

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.

The Swift type R springs are linear springs. see post #177 in the following link. This person (CFZ) has a detail review of the springs on this site as well.

SWIFT Springs in Production

Anyway, linear or not, just get what you feel is best for your driving style. I have Swift and like it.

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.
