[jdms2000racer]

what swy bars will i need for my car front upper and front lower?
do they make rear sway bars rear upper and reatr lower?
who make a good brnad dcor... i dont know please make suggestions????
thank you

Okay Eric . . you're gonna be fine. Deep breaths son. Deep breaths, n' lettum out slow.
I'm at a bit of a loss as to the spelling/meaning of some of your message. It appears that you're askin' about upper n' lower????? anti-sway bars for both ends of the car, but as your message was pretty garbled, could you please 10-3 that? (Say again)
On the chance that I'm understandin' you right: the car already comes with substantial anti-sway bars. No self-respectin' sports car wouldn't. There's only one anti-sway bar at each end.
As for the brnad dcor . . well . . I guess that's jus' gonna hafta wait until your next message.
A little less caffiene Eric. You'll be surprised at what you've been missin'.
Be well.

Not to be picky, but the correct terminology is "anti-roll bars". People stopped calling them sway-bars in the 1970s.

You're absolutely right slim, but as incorrect as it is, n' as many times as I've explained how an anti-sway bar would help you stay level in a corner and a "sway bar" would likely, by it's description, help you to lean further in a corner, people have never stopped callin' 'em "sway-bars", 70s or not. But it's nice to know that I'm not the only one.
Be well.

Do a hunt around for Cusco Strutbars (or strut brace) I've got a carbon fibre cusco upper strut brace and a lower brace.
I've not got the rear brace yet but they do make one that's supposed to be quite good.

Upper brace


I got mine from here http://www.takakaira.com/
I'm sure there are US dealers.

The front end braces do make a big difference in steering response. Much tighter feel now.
Cusco arn't the only suppliers obviously. Do a hunt around and see what you can find.

Strut braces and anti-roll bars are two totally different things.

Strut braces increase chassis rigidity and reduce flex. This amounts to quicker chassis reactions as there is less deflection in the car's structure.

Anti-roll bars increase the car's roll stiffness. They are mounted directly to the suspension system in one way or another. They work by reducing the difference in suspension travel between two suspension members. Playing with anti-roll bar settings has a HUGE impact on vehicle dynamics.

My hat's off to ya fletch. I'da never guessed shock tower braces. Thanx for the info.

fletch;
That carbon fibre actually works? It's not like carbon fibre over steel or aluminum? I ain't doubtin' you, but when I look at it all I can see is it bowin' like a downhill ski. That really works huh?

Whiteline make all sorts of swaybars/suspension mods. I'm not sure if they have one for the s2000 (you can download and go through their catalog).

Thanx slim, that's an accurate description of what we're talkin' about here. It sounds like you weren't just sittin' back n' doin' the drivin' while others took care of the design n' wrenchin'. Yer makin' noises like a knuckle-buster.
Here's to all the wrench people. We'd all be walkin' if it wasn't fer them.

Not only that, but it has those two potential pivot points where the CF is attached to the Alu mounts. Even if it is CF wrapped around Alu (for looks), wouldn't it be better to have a single welded piece of metal between the two points you're trying to keep from moving independently? For looks, I do like CF though

[slimjim8201]

I would guess it is carbon fiber wrapped steel. Take an aluminum bar of that size and you could deflect it with your arms if you aren't a weenie-man. The pivot points are ok. If you look at this from a statics point of view, you will see that it won't make much difference if you change the junction from a revolute joint (pivot) to a fixed joint. I know there are some fellow engineers out there right??

From my experience with carbon fiber, even if the composite was strengthed with a honeycomb core, a steel bar of equivalent size would still be stronger. I'll look into it.

By the way, that is one badass intake box. Shoot us some info on that beauty.

[Java Junky]

Whew! You guys don't miss much do you? I humbly stand aside takin' notes. 'Got a real nice (productive) mix of input goin' on here. ' has all the earmarks of an S2000 think-tank. That kinda thing don't happen often. Somebody roll camera.
(That IS a helluvan impressive lookin' intake you've got there fletch)
Hope everybody's well.

Terminology Alert!!! I jus' checked out whiteline n' they're advertisin' "swaybars".
Although, I believe they're down under where the water circles in the opposite direction when it goes down the drain, so maybe . . . alright, alright . . I'm goin'.
Be well.

I can add a little info here as it pertains to the original questions- at least as much as I can understand that mess.

Best front sway/ roll/ anti-sway/ anti-roll (whatever) bar that I have found and many S2K autoXer's would agree is the Comptech Competition Adjustable one. Strong as any out there and a MUST if you autoX seriously.
As for the rear. I tried going to a larger rear (again Comptech, but none adjustable) and did find less lean in the rear, but it developed SNAP oversteer. Let me tell you, THAT will wake you up quick. I went back to the stock rear bar.
The strut tower brace (STB) is a help and many people like the X braces as well. I didn't notice any major improvements with the STB or X brace, but I do have them on.

This is simply what I have been able to learn on my car with my driving style, not a recommendation.

[Java Junky]

Go;
The car that you're Xin', is it the earlier 2000 or the later "2200"? I'm just wonderin' if the latter would be as effected by the heavier rear bar as would the earlier cars, considerin' the suspension n' wheel/tire changes. Although, if you're already Xin' the thing, I guess even if you're runnin' an early one it's no doubt a match for the later ones suspension-wize.
Thanx for the input. Much appreciated.

Well... You guys are spot on. It's not actually a full CF strut it is CF wrapped around steal (At least, I think it's steal and not an alloy).
Your right of course. A full Carbon one wouldn't give enough rigidity.

The Air intake is a "copy" of the Mugen CAI. The Mugen model is around $1,300. This one was nearer $600-700.
But you could tell.
I had to do quite a bit of sanding and shaving on the edges where the intake fits in, because the moulding wasn't spot on. But I'm pleased with the results.

Got it from a supplier on ebay. Can't remember the name at the moment.
I'll have a hunt around when I get home if anyone is interested.

I agree.
I've recently heard from a friend who put a rear brace on. He said that the rear is much snappier now. It provides much less warning of impending oversteer.
I'm not liking the sound of that, so I think I'll be sticking to stock on the back end.
