Nismo VS Sport Package Springs, Struts and Shocks
 

I am hoping someone can help with this suspension component question.

I know the springs are different between the Nismo and the Sport Package but are the front struts and rear shocks different?

Thanks,

Im almost 100% that they are different...

Check the part numbers.

if i recall.. they are different

i've been looking this stuff up for weeks. They are definitely different. The rebound and compression are slightly higher on the nismo, though not enough to really make a good difference. I believe the nismo s tune struts are even higher compression and rebound than the oe nismo

I just install the Swift Springs and rear camber arms to my Z and work perfect... love the difference!

Is this a mod worth doing?

what mod? struts? or struts taken from a nismo?

struts from a nismo, not worth the time, but a good set of struts is better for performance than a set of springs. However, a good set of struts will run you at least 1k$ and even as high as 12k$ for fancy ones.

Swift springs??? hell yeah!!! do a research on the forum and you would see

I have the nismo springs and would like to know what struts to match. It is a daily driver(65k) and not tracked. I just want less lean for aggressive driving and slight more stiffness for bad roads. I already have aftermarket fr.swaybar. KYB or koni good choice? which?

I'm in the same boat. Koni > KYB, but neither is as good as a nicer higher end model. If cost isn't an issue They have custom dampeners that are about 2800$ a set. Set of Koni will run you around 1k, but they're not as reliable in the adjustment as higher end models are.

I have a 370Z with the perfomance package suspension, wanted to know if it was worth the effort to replace springs, front struts and rear shocks with OEM Nismo?

no, not really. The consensus around this site seems to be

For looks: go Swift springs

For performance and looks: go coilover (not comfy though)

for performance and you don't care about looks: a set of good struts (however a lot of people here will disagree with the last bit because they care about looks or they haven't had enough hands on racing experience)

It all depends on what you want. I personally think the stock height is way too low, so I'm not going any lower, just getting better dampeners soon. If i pony up the money I'll have some custom built double adjustables for around $3k, but otherwise Koni are a good choice at $1k

I honestly thought I was the only person with the above opinion on here. :tiphat:

Sort of -- they are stiffer and perform better, but really, the major advantage is that they are inexpensive.

If you want better than OEM on a budget, go for it. If you have a little cash to play with, I say pass on coilovers and get a set of Koni yellows plus swift springs.

OEM base: ?
OEM base + sport: black spring and strut
Nismo 370Z: red spring, silver strut
Nismo S-Tune: red spring, silver strut
Nismo 370 RC: "nissan genuine"

As far as I can see it, these would be the different suspension setups. I am not sure if the valving is the same for USDM v Euro v JDM cars, or if the suspension was changed at all over the years. Also not sure if the Nismo S-Tune is the same as the Nismo 370Z. Also It would be awesome to find out the valving and spring rates for the different OEM components.

FWIW I replaced my sport package suspension with used parts (still lower mileage than mine) form a Nismo 370Z. Ride is much stiffer and more responsive. No change in height.

I agree, but from a performance standpoint i'd never get swift springs. They're great for lowering your height while keeping the ride comfy and not blowing your stock strut, but they are progressive springs, and progressive springs are terrible for performance because they're not linear. With hard driving you'll get snap under and over steer. Either keep the stock springs or go to stiffer non-progressive springs...but that's for performance only. if you want a drop that's a different story

If you are just after a drop, take 3/4 a coil off the springs :tup:

HAHAHA! In true Honda style! :stirthepot:

My suggestion is go drive a nismo and see if you like the stiffness the nismo brings then you should be able to answer your own question.

You will be the one driving your Z not us.

Whats comfortable with me might not be so with you.

Imo my coilovers made me feel Im driving a sports car.

nismo springs on a base? will lift your car in the front especially. someone already tried that and ended up running swifts.

FYI... Swift springs are linear and not progressive. IMO, they are probably one of the better after-market springs. There is plenty of info out there.

Going from Base+Sport Package to Base+Nismo from what I've read the ride height will be lowered 0.4", is this true?

I'm not going lower then stock. I have replaced the black plastic piece under the spoiler twice now. Gets beat up on the track.

If you're talking springs, then Nismo is apparently taller.

Haha, yeah that's pretty beat up on mine too now. I'm considering custom fabbing an under tray that has a splitter coming off to add some much needed front end downforce at high speed cornering, and keep things from getting thrashed on the track.

They sure don't look linear. Not arguing they're bad springs, they just aren't ideal for a performance situation. Anything that's supposedly stiffer but designed to mate with the stock dampeners is most of the time progressive and designed for looks and feel over performance.

:iagree: i already have the Swuft springs and i love them... eventually im going to buy the Koni struts for sure....

:iagree: i come from an Sti with BC Racing Coilovers and a few more suspension upgrades and trust me when i install the Swift springs on my 2013 Z + Sport Package i fall in love... the call turn perfect, drop was perfect... best springs i ever run on a car....
Dude i dont know were do you find the info... but you are completely wrong about Swift Springs.... the performance from those springs i cant tell you from my personal experience that work 99% perfect... and im runing just the spring with OEM Struts and SPC rear camber arms.... My car is a DD, i spend 70% of my trip from my house to my work in turns and the other 30% on highway... the car run just perfect... the drop its perfect.... everything its perfect.... even making Touge hahaha!! just do a research and you would see what im talking about ;) I know read somewhere that people use the KW coilovers with Swift Springs... i think was on a build on a coverage from Speedhunters...

You driving to work has nothing to do with performance. Sorry, but when I'm talking performance I'm speaking track, autox, time attack, etc. Swift does make a great spring, but we're talking linear springs designed to go on coilovers or designed to be mated with a high end dampener.

They're stiffer, lower, and progressive which means you don't have the amount of suspension travel you actually need to keep the car planted, but because of the stiffness you feel like you're cornering better.

Again I'm talking performance only, i'm sure they're great as a DD and you like the drop.

when i say i expend 70% of my trip in turns... do you think that i take it all the time like a grand pa:shakes head: looool!!! dude!!! shame on you... who have an sport car to drive slow.... BTW i dont need to drive on a track when the street that i use looks like a nurburgring track hahaha!!! of course i know when i do this runs... i dont want hurt no one... anyway they are good springs and everyone can think that they want... but my 2 cents... when you do it use the correct info... if you dont like it well you can use other way... i just mention the Swift Springs cause i buy them and a lot of people use this springs for the track, auto x, etc.... By the way i do my research first to see if they work ;) after read a lot of pages and thread... they are the best for the pocket:p

I have a sports car to drive it slow. It goes the speed limit to work and around town every once in a while. most of the time it sits in the garage, until i pull it out to use it for auto-x, track,time attack, and this next year i'll attempt a hill climb for the first time. I answered a performance minded question with a performance minded answer. What you feel works for your daily commute is subjective

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 ;)

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! :)

Perfect...:tup: Thanks bro!!! happy weekend to you too :tup:

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.

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.

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