Sway bar opinions...

[Ryan of Velocity]

Just wanted to post and get some of your guys' opinions on sway bar sizing and materials. We're (Works Yamaguchi) are starting our own product line called D'Stage and the S13/S14/Z32 sway bars are going to be one of first releases. I don't want to violate any rules so I'm not going to turn this into an ad. lol.

Anywho right now the sizing on our test set is 31mm (front) and 23mm (rear). For comparison:

Front Rear

Stock 27.2mm 16mm

Sustec 27mm 20.6mm

Largus 31.5mm 27.5mm

Tanabe 30.4mm 22mm

Whiteline 27mm 22mm

D'Stage 31mm 23mm


From what I've gathered alot of people are intersted in Largus size sway bars so we decided to produce two types. One the sizes above and a larger Largus size set. 32mm front and 28mm rear.

I just wanted hear everyones opinion on sizing so we can put out the ideal set.

Also these are going to be available in either chromoly or sprung steel. Any opinions on materials? We are working with guys who have years of experience engineering components for the IRL, F1, etc.. but I wanted to know what you guys thought since you are the ones we are trying to sell these parts too. lol.

And admin, if this message violates any rules let me know. lol.

Brian's thoughts:

make these bars utilize stock endlinks.
paint them a ridiculous colour, sparkly green.
i like your "largus sizing".
chromoly seems like a good material.
do you happen to know Cusco's sizes for s14 off the top of your head? if you have to search for it, dont bother.

[Ryan of Velocity]

Not sure about the Cusco sizing. The sways are going to be powdercoated a "sparkly" purple. lol.

We're going to make a few versions. One being for use with the stock end-links. We're also working on our own adjustable endlinks as well.

[Dousan_PG]

my suggestion:

i love the LARGUS size idea. maybe wont sell as much but to the 'bigger is better' folks haha..if i can get my suspension up to match oh its freakin' on!

but anyways, i say something near largus and something LARGER then Whiteline
why? whiteline is so common a bit larger gives folks another option.

yes im all for the stock endlink style setup. i know pretty mcuh all japanese sway bars run taht style setup..works perfect

i like the test set sizing

[Cthulhu]

Brian, Cusco size for the s14 is 30mm front, 21mm rear. Also, for comparison's sake the tanabe s14 rear sway bar is 27.5mm, according to their website.

[ZodiacSR]

Correct, Cusco is F: 30mm and R: 21mm

If you make them F: 32mm and R: 28mm, I will buy a set. For color, I'm plain and simple... black for me.

Please offer new D bushings and D brackets to accomadate the larger size bar.

And yes, please allow them to be able to use factory endlinks.

Just my opinion

[BadMoJo]

I like the sound of the Largus sizes. And I like the idea of a crazy sparkly color.

As far as endlinks go... stock type or maybe a cool setup with heim joints like Don Nimi has on his whiteline bars.

[thx247]

sprung steel? Why not unobtainium?

[DSC]

BIGGER IS BETTER!


But really, I do have some questions.

You asked us what material we prefer but I don't know anything about them...price, weight, etc...
I say you and your engineers just pick one for us thats the best comprimise between price and performance.

My other question is about the different sizes.
How big is too big? Is there any "matching" that should happen with the rest of your suspension and the size of your sway bar? apex n1 vs stock springs and shocks...should they run the same bar size? I mean...is it possible to have a bar so big it will not allow the springs to really do their job while cornering or any other combinations that would have negative side effects?

I like the idea of being able to adjust the effective length of the bar. I think whiteline had a good idea but just implemented it poorly. Is your adjustable design going to use hiem joints/pillow balls? When will they be out? And any ideas HOW MUCH $? or would that make it an ad

[Steeles]

I think anything in the range of the "established" companies will be fine for the 240 crowd. especially if you offer them at a good price you give yourself the ability to say "we got largus sized bars at half/fraction/less price"

so that would give you front sizing from 27-32mm and rears from 17-23mm to offer.

[DSC]

16-28mm >

Hey, I have an ST front sway (any idea on the size of those?) should I match it with a 23mm or 28mm rear?

[kandyflip445]

I like the largus sizing. But I'm with DSC pick a material that works. I don't know anything about materials. For the color, I'd take black over anything else, but it's just preference. If it works I'll buy it.

[Steeles]

ST are 28.6mm front and 20.6mm rear

[DSC]

LOL, ST 28.6mm/f DS 28mm/r would be a sick setup

Anybody care to guess if this would be fun or not drivable stupid dangerous?

[Chernobyl]

Please allow the option to buy just the front or rear bar seperately as well. If you plan to supply front D brackets and urethane bushings with the kit, please please make sure they fit (unlike ST crap). Also, I agree on the stock endlink idea, but they could use some urethane bushings at the ends that mount to the suspension, so if you could provide those, that'd be great (although I'm sure these can be had from other companies if you choose not to provide them). And most importantly, I'd like to see thicker sway bars at a very competitive price, so "simpler is better" I think (as in, no funky adjustability and heim joints and all that). Less production costs for you and lower prices for us.

[CoasTek240]

big sway bars + damn decent prices= me being a happy camper, b/c i'm buying them asap.

[kuruptR]

Pricing.... $175.00 us

[Frappe]

This may well be a really stupid question,
but why doesn't anyone make aluminum sway bars?
No rust, lighter...is it a flexing issue? or a strength issue?

[TBreu007]

I'm going to disagree on not having heim joints. Heim joints offer the best for any suspension component...like Papa John says, "better ingredients make better pizza."
There's tons of sway bars out there; you can make sway bars like all the rest, or you can make the best. I don't see what is so intimidating about heim/spherical joints. Drive a car with spherical bearings in the suspension or sway bars, and you will understand why they are the best.

My suggestion:
How about a full race setup with spherical end links and adjustability to remove or add bar preload.
Straight NASCAR style splined bar and aluminum arms.
Spherical swaybar mounts.

In my race car, with Whiteline bars and 450/330 spring rates and race tires, the Whiteline rear bar was way overpowered, and the bent nature of the front bar and urethane mounts leaves much to be desired in the way of predictability. I'm in the market for some better bars...do you want a racer for some real R&D?

[JasonNagra]

I have been wating for well designed and cost effecive sways for my S13 for a while now! SWEET.

[West]

If you really want to set yourself above the rest design something like Porsche markets have for their cars. Like the sway bar below. Eliminate the bending and heat treating required when bending bars that can cause fatigue. You could also make these hallow to reduce weight. Of course, I doubt this is even possible with the design of our undercarriage.



If you want something different, then consider a tubular design sway bar, to save weight. The thicker the outside diameter the better. They can perform almost as good as a bar that is solid and the same thickness. Also, it matters how they are made with tubular design. IIRC, rolled design is better then gun drilled, which you would only see a slight decrease in weight.

Damn.. this porsche ones look hot too..

Sorry I didn't respond sooner. Been running around like a mad man. Our goal is of course to have the best of what is out there BUT we also want to have an affordable alternative which is why we are releasing sway bar kits that utilize the stock endlinks first. Our own adjustable end-links are in-fact going to be spherical but they aren't ready for "production" as of yet.

[Soulja]

If we pick up the sways, are we going to be able to get the endlinks separately later when they are out? Or will they only be sold as a package with the bars?
Oh, and hurry up and get the bars in production and out for sale.

[sykikchimp]

Larger than whiteline bars with adjustability.

DSC - 28 F and rear? that would cause what Mark used to call, "tail out Jackassery!"

Sure can. We will definantly be selling the endlinks separately. Someone mentioned earlier about not buying a set but just a front or rear bar and that's fine as well. Like I mentioned on another thread as well, we'll be willing to do custom sizes if someone has something specific that they want. I threw the Largus size bars into the mix at Dousans behest. lol.

The s13/s14 bars should be released by the end of this month.

[Soulja]

Are these going to $175 each, or a pair?

Ryan never said they would be 175. that was Kurupt REQUESTING that price for them

[Brian]

any updates of how these are turning out? i am most curious about them and will be getting a set after they are released.

[Var]

so was whiteline lying about having too large of a rear sway bar? or do you guys actually want to slide by the slightest steering inupt? I mean a 28mm rear bar would render your car useless for traction driving right?
