sf180th · 02-09-2007, 08:08 PM

Just ordered the TRD Sway bar along with TRD lowering springs, this should make a diffrence!

*Chris07LB* · 02-09-2007, 08:19 PM

good deal.

St_G · 02-12-2007, 02:18 PM

Ordered the sway bar from Sparks last night. Was going to order the springs too, but I spent damn near $150 on dinner Friday night (sort of on accident) so those will have to wait while I get my alarm and window tinting installed.

put the trd sway bar on today and it looks nice. not sure if it does anything yet, but springs are coming next......

RocklandToyota,I have a few questions about your sig.Do those TC mats have a TC logo or Scion logo?Do they fit the Yaris perfectly,does the driver side mat use the 2 clips to stay in place?
Why did you use the XB neon light package,is it the same package for the Yaris,just cheaper?

eco · 03-04-2007, 07:57 AM

Ohya,I have my rear TRD bar installed,and my ass is alot smoother,like a baby's.

Hmm I wonder if the torsion beam is an independent type of suspension. On my Accord Euro (very similar to your Acura TSX in the USA) has independent rear suspension, and I could feel a huge improvement by upgrading the stock swaybar, there is more oversteer. But since the swaybar acts to limit the movements between the left and right arms, it requires the left arm to be independent to the right one. In our case, the torsion beam connects the left and right suspension, hence by adding an extra swaybar, it increases the "stiffness" of the torsion beam. However since torsion beam is a non independent type suspension, the increase of handling performance will be less than if it was fitted on an independent type rear suspension.

This could be the reason why he said adding a swaybar on a torsion beam suspension does not do s@#!. I actually own a liftback yaris and I am thinking to get the swaybar too. But so far I have not seen any convincing words which can make me click the buy it now button.

blueskana · 06-24-2007, 07:57 AM

How would a conventional, chassis-mounted, linkage-drop down arm system work with a trorsion-beam suspension design? I can see how the trd one basically just stiffens up the beam, but couldn't you take the sway bar, mount it to the body on poly bushings and connect it to the shock mounts on short linkage arms? If you are looking for a truly stiffened, 3-wheel cornering without having to have insanely high spring rates, wouldn't that do the trick? Am I totally smoking crack here or what? Somebody who understands this better help me out.

Oh, and this is my first post, Hello everyone! :)

OgDogg · 09-05-2007, 10:53 PM

I gots me a sway bar that I paid "big bucks" for. :)

SDsurfrider · 09-06-2007, 01:41 AM

There are a bunch of good sources online dealing with suspension setups and how changes will affect handling. A quick google search turned up these examples:

http://auto.howstuffworks.com/question432.htm
http://en.wikipedia.org/wiki/Anti-roll_bar

I have a porsche 924s autoXer and these are from those forums(I know the 924s is not the yaris but it too has a torsion system rear susp):

Anyways when I put on the rear sway bar on that car I immediately noticed a difference, more so because it is RWD though.

Milk Dud · 12-01-2008, 10:39 PM

I see you've been mentioning about descent tires to go along with the sway bar. Just wondering what sort of tires you'd recommend. I'm thinking of buying 16s and a sway bar for my girlfriend's 07 Sedan for Christmas. Also, anyone experienced any bad things with 205/55R16s on stock springs?

uncleyaris · 12-02-2008, 12:34 AM

The sway itself is big difference. I organized a GB on them and you will not be disappointed!!!

Yes, TRD and others.
In the case of sway-bar, same part for sedan and HB.
I installed mine weeks before the other TRD parts.
BIG improvement! Reduced body roll (sportier) and reduced cross-wind effect on the highway (safety) providing a much more relaxing ride.

Ultra Racing 19mm sway bar (liftback and sedan), same size and quality as TRD, $30+ cheaper:

Ultra Racing 23mm sway bar (liftback and sedan), beefier, more anti-roll in turns:

Some say they make no difference while others say they do. Maybe it's more to do with variations in our nervous systems abilities to feel the differences or lack there of. All I know is that before I put mine on it didn't handle sharp turns without a fight where now it fights noticeably less. For my nervous system they were worth every cent.

Pokey drivers may not notice the flattened cornering by adding an anti-sway bar but it would be hard not to appreciate the increased cross-wind stability if you drive on the freeway with strong winds and semi's abound.
I'd like to sample the 23mm bar although it's billed as being for 'the track', not street.

RedRide · 07-18-2010, 10:43 PM

I have the 23mm bar for steet use and I love it.
I can't see how it would be a problem for a DD for anyone who has any semblance of driving skills.

It also make freeway driving much safer because fast, emerency lane chages, etc are much more secure and stable.
