View Full Version : Sway Bar!
Are there any REAR sway bars available for the yaris yet?? C-ONE has a front sway bar but a rear sway bar would create more oversteer (i think) which is what i want!

I hope they come out with a front sway bar also. I'll be waiting to buy the set.

sounds good, any chance of a front/rear kit to be released?

any idea on what the cost would be?

I would say under $150 but need to await their final decision!
under 150?!!! for a rear sway bar?!! OMG!! drool....

Most of our Progress Tech Sway Bars are around $164.95 - $149.95 DELIVERED.... However I know Suspension Techniques offers front and rear sway bar kits... but I do not know if they are working on anything for the Yaris at this time.

Im sure if you did a Group Buy, you would have LOTS of takers... esp. at a price like that.. or lower in a GB situation! :headbang:

One thing you need to keep in mind is that since the Yaris does not come with a rear bar they are going to have to include mounting brackets and such which will drive the price up. The install kit for a rear bar on my Pt cruiser was $100.
I will definitely snap a rear bar up after winter!

No problems... we work directly with the manufacturers... As soon as they release the pricing... I will post... the part number is already available.
This is terrific news! I had a Progress Tech on my 05 xB and it was just what the doctor ordered. I looked at my Yaris hatch on the rack and just couldn't see how there would be any room for a fit . . but fortunately somebody worked it out.
For the average guy, a rear sway is all you need to have fun with. Can't wait.

I would be very interested in a F/R set of sway bars. GROUP BUY!!!!!!!!!!

do sway bars really help

Upgraded sway bars (in this case thicker in the front and added in the back) will stabilize the car in hard cornering by counteracting lean induced by gravity. I will say that the stock set up on the Yaris is great; however, if you really want to extract the most from the car, thicker/stronger bars will help. It should be noted that its best to lower the center of gravity before tightening the car with sway bars to keep the handling more predictable. A high center of gravity with thick sway bars make the car a bit unstable in hard turns. This is one of the reasons why there is no sway bar on the car.
Correction: No rear sway bar in the car. The front is there but thin due to ride height and lack of a bar in the back...sorry, long day...heh.

yes they do, but don't go to radical, as it can cause a rear tire to lift on hard cornering...

My old Neon used to lift the inside rear tire and it was stock, on sticky radials.
Going with too large of a sway bar can cause snap overseer which is very dangerous. Perhaps there will be an adjustable type bar. That would be ideal for people wanting to have the best of all worlds.

and this a bad thing? that wheel isn't doing anything anyway.
it's bad on RWD/AWD but on FWD it's pretty common, it's a funny site too at an autox. :headbang:

Leo from Weapon R has one almost ready. Looks pretty good...! I also saw the bar. However, what I saw was a rear strut tower brace, not a sway bar. I was pretty beefy looking and was made of stainless steel tubing of about 2" diameter.

There is a sway bar in the back... It's what the wheels are attacked to!:laugh:
But really, the torsion style suspension utilizes "torsion a.k.a. spring" in the components. That swaybar shaped beam the wheels/brakes/springs/shocks and such are attached to is in fact a swaybar.

Ah...yes, of course. point well taken. I guess it would help to look under the car...heh.
either way i think we can all agree on trying to set up an immediate group buy once sumthing good comes out!
so vendors... if u want to sell like 10 sway bars...

I stopped by Progress and they said the rear sway bar is in production and it should be released sometime after the New Year. It's similar in design to the Xb bar except that the mounting bracket connects to our spring bucket instead of the welded on brackets that the Xb has. 22mm diameter. No retail pricing yet, but I will try to organize a group buy as soon as they are available.

When adding a rear sway bar to achieve the improved handling, would the addition of a larger-diameter front sway bar be recommended as well?

considering this car does not have a rear bar I do not think it would be necessary to upgrade the front bar. However if there is a big difference in the bars then if the front bar is to thin compared to the stronger rear bar then you may experience some understeering.

the basics of anti sway bars really short
stiff front = more rear traction
stiff rear = more front traction
side effect of stiff front = less camber change during compression which is a good thing.
So, who's going to be guinea pig?
Caution to those of us who are in the snow belt, too much swaybar in the back is a recipe for disaster.
There seems to be some mixed angst over this rear sway bar thing. I had a Progress on my xB and it was perfect! It kept the tail from wagging and gave it a more neutral steering effect. Lift off the throttle and the tail would rotate out in a CONTROLLED fashion.
If you increase the front along with the rear you have essentially done nothing but reduce body lean and kept understeer the same.

the front bar should always be larger then the rear bar, now should it be 15/0 (f/r)? no.
more like 22/20 (f/r) or 18/16.
Russ, if that were true these companies wouldn't be selling a singular rear sway they would only sell matched sets. The rear-only bar helps the car drive and handle more like a rear drive car.

if you think companies only sell what's best for performance you're either not paying attention or don't want to believe it.
if a company did only sell "sets" they'd be limiting their customer base significantly as people are cheap and like to do things in stages or to their preference even if it is negatively affecting overall performance.
my statements come from class winning autoxers and track drivers not from what companies do or do not decide to push in their marketing campaigns.
most people havn't driven a rear drive car that "feels" like a rear drive car. most rear drive cars drive like a fwd car except when you stand on the gas with the wheel turned the rear wheels spin instead of the fronts.
i'd much rather have my car GRIP like a mofo then dorifto like NOB.

companies like Hotchkis who DO sell sets, IE the scion xA/B have severely undersized the rear bar.. no one wants to have people look down on their company for making spin happy econoboxes.

i can vouch for Progress. love their rear bar on my xA.. but i will be adding a Whiteline rear bar in addition to the Progress, help stiffen things up even more

wait, so your going to have two rear sway bars?
anyone ever seen the hardcore rear suspensions on modern touring cars? some of them use beams, i remember an article in a race engineering mag. pretty cool stuff, very fascinating.

I'll drop by the office tomorrow on my lunch break and update everyone.

I'm pretty sure the Sedan uses the same rear trailing arm and the sway bar will fit. I'll ask Progress tomorrow if they can confirm this.
