Sway Bars: What did you choose & why?

[trackratZ]

Far from an expert here, but going in my consideration of bars was how much over stock they added to stiffness. Quality important for sure, but if the numbers given by the robot below are accurate (or even just representative), the Z1's may be too stiff for some even at their softest setting. Your tires matter also. Anyway point being not all sway bars are the same, require different amounts and type of maintenance, etc. So think about your goals and other equipment.

Swaybars both front and rear are made to balance optimize handling, with some adjustments given hopefully at both ends. Those numbers are interesting but have similar numbers for the rear bars? Would be cool to have.

Then of course when you add springs or coilovers the tuning gets more complicated. Again, all depends on your use.

I did the same thing. Went to every site and wrote down all of the info I could find on the stiffness % over stock. Z1 seemed to have too much rear bar to me. I didn’t want the Nismo or ST based on the issues that were found by a few members. The Stillen if memory serves, had more adjustment on the front bar which I knew from research along side how my brain is wired (wrong or not), I didn’t want. Hotchkis had no adjustment on the front bar at all. Eibach had more adjustment on the rear and I knew I could trust them. So that was my process. The Eibach front on the stiffest setting feals great and I don’t think I will mess with that. I’m on the softest rear setting and the jury is still out. There is a possibility that once I go with a square tire setup, the Eibach rear might be too stiff. Although, I haven’t yet pushed it hard in my usual test corners to nail that down. I’m definitely happy with my purchase. Hope this info helps someone that is still searching.

What I normally do is, we have a slightly banked fwy interchange that is about 300 deg near home. At times when it's clear, that's where I test cornering balance with setups, been doing that too many times. There's a long straight leading up to that curve so I can carry speed as much as possible to find limits, 4 wheel drifts or rear/front, whatever, then home to adjust suspension, rinse and repeat. Not recommending this on public roads but it's just me LOL.

you’re mixing up the Nismo model with Nismo parts separately available for same

this might be a shock but…

car manufacturers dont make all their own stuff. Some is made by other car manufacturers. Some is contracted out to afternarket companies. Some is contracted out to specialists.
Similarly, the optional parts catalog is full of rebranded stuff

some is good
some is ok
some is bad

some is made in japan
some is made in china
Vietnam
Germany
Usa
Uk


Sure seems like this sway bar is shit

I get that but, as far as I've seen from this forum, parts being sold as "Nismo" parts are not what Nissan uses for their Nismo models. So, the Nismo store is not the same...
Did I miss something?

What is unclear?

"Nismo" is just a name. It can refer to this:

Omori Factory

Or these (sold at the above, but not made by Nismo)

Or this

is there a "Nismo" store front?

Sure
https://nismoparts.nissanusa.com/

can your dealer order "nismo" parts?
just get the part number

I am again baffled by what you're asking

 

[ZMidlife]

So all the nismo talk.
Who is on lowering springs with sways?
Im still going back and forth if a street car needs COs vs a spring & sway

read the earlier pages of this thread

The actual Nismo bars from the Z nismo are another option, you can buy them for around the same price as aftermarket bars from the right dealer and they are larger than the performance bars.

AFAIK the bars from Z Nimso models(not to be confused with the aftermarket Nismo bar) is tubular 28mm rear and 29mm(solid? not sure here) front.


Edit: I'm only guessing solid front because I can't imagine the factory having front and rear bar rates so similar to one another, I don't have eyes on the parts yet.

big difference with Z1 bars - rear are similar 138 / 214%.

what is their purpose for such a big jump over OEM. Track?

Looking at Eibach installation info - the firm setting is recommend for dry and smooth pavement…

Surprised this is Z1’s only offering - seems like they would also offer a milder version for street & wife approved…

That version is called Stillen

When I was researching swaybars I could not make sense of what Z1 was trying to accomplish with those rates, other than maybe for a track car on slicks with gobs of traction.

Eibach, as always, offers a very nicely balanced package.

My .02. The whole Nismo/ not Nismo, Nismo Nissan OEM/ Nissan parts counter aftermarket Nismo thing is being way overthought and worried about. The Nismo sway bar breaking issue is a very weird fluke and is probably something that was found out and corrected. Especially due to where and how they are sheering off. KW/ST is one of the most prestigious suspension companies out there. It was probably an issue with the steel that they sourced and not the design or execution. For those that have had the issue, I get it. It sucks. The Nismo coilovers are literally a KW product. Just a lower end than the KW V3. If you’re dead set on having everything be a factory Nissan part, then just realize that this idea isn’t a thing. The shocks from the factory are made by Tokico. Coil springs are made by only a hand full of companies in the world in the grand scheme and I’m sure Nissan out sources these as well. Factory anti sway bars are probably the same. OEM chooses companies that give them a great deal so they can make more money. Choose a brand that tickles your fancy that are tried and true and you will probably be happy. Eibach, Hotchkis, KW, Ohlins, etc. all good companies that have been at it for years. The factory Nismo bars are not some magic masterfully crafted item that were woven together by Japanese virgins at the top of Mt Fuji. They are probably made in the same place as the non Nismo bars. Cheers

“Need” is a very subjective misused word in the performance Automotive realm.

Personally. I think (based on years of driving and upgrading) that the factory shocks belong on a Sentra driven by your Grandma, and not a Sports coupe. They belong on my garage floor. So for that matter, due to the fact that no one makes a Motorsport replacement like Bilstein or Koni, I think that coilovers are the way to go. The factory shocks can’t even control the factory spring rates well unless you’re just cruising to the grocery store so how can they control higher rates well? Now, will springs and sways make the car feel more sporty? Yes. Lower center of gravity, and a little less nose dive under hard braking, and a little less squat under acceleration. The sways will give you more roll resistance and if you choose a good adjustable set, it can give you something to tinker with to help balance out the chassis, especially once you get stickier tires or change tire sizes. BUT…. a good set of coilovers will transform the way the car drives in every way. So if the question is A) Coilovers or B) springs and sways, then the answer is A. But. Coilovers and sways are fantastic.

Big reason is this. When you have a shock that has a range of motion from static to compressed to the point of hitting a bump stop, and then you add a lowering spring, you have just reduced the travel drastically and will probably contact the bump stops quite often which increases spring rate drastically all of a sudden causing loss of traction on that wheel in a corner. A coilover is designed around driving at a lowered state with less range of motion thus keeping you in control more often.

Hope this helps sir!

Are you baffled? or are you slow?
I'll try to put it easier for you... does the Nismo Department at Nissan orders their parts from the places you mentioned? after reading other comments that make sense, the answer is no.
You say that Nismo is just a name... I thought the original idea of "Nismo" as far as Nissan is concerned was Nissan's department for special model versions.
You may have all the answers (or so you think) but some of us are new at this Nissan thing. So, if you don't have the patience to get involved in these discussions, then stay silent; "smart ass answers" are uncalled for...

Perfectly put. Now I get it. That means that the "Nismo Store" has nothing to do with my Nissan Z Nismo.
