2014 SE TRD rear sway bar installation problem

[VaultTec]

Can you guys post some photos of it installed? Don't really like looking at the stock photos I find online.

Glad to hear you were able to install with no problems. It's a great mod, as you have discovered.

We had a rough time getting the two primary bolts loosened, so that we could install the sway bar in the occupied bolt-holes. We had to jack up the rear end and take off the rear wheels to get the space/angles needed to loosen up those suckers. Luckily, my nephew has a lot of do-it-yourself tools and heavy-duty jacks (he does a lot of work/mods on his 1999 Lexus sports-coupe). I would rather have the extra bolts and not need them, than need those variant-thread bolts and not have them. Plus, with my luck, my SE should have had those dampeners installed, but didn't due to some factory-assembly oversight. I won't know until someone else here with a 2015/2016 SE crawls up under their car and takes a look to confirm.

I will try to take some pics tomorrow after work. Most of the sway bar is pretty concealed, and tucks right up into the groove of the main beam, running between the two rear wheels. You really only see the red sway bar where it swoops down on either end to where it bolts onto the wheel/brake/shock area.

Here are some pics taken from another thread on YarisWorld (from a 2012 Yaris), that sort of illustrates what I just said above. The 2015/2016 really isn't any different underneath there as the 2012-2014, or the 2007-2011 for that matter.

I can confirm that my 2016 SE doesn't have the dynamic dampers. Thanks for the photos. I will be ordering one later today. Would be be possible to get a photo from the back showing some of the rear bumper? I don't want too much of the bar exposed. It'll look weird seeing a red bar on a white car. I'm just trying to get an idea of how much would be seen from the views of a car behind me.

On my 2014 it is pretty much invisible from behind.

Yep, the only part of the sway bar you can see is the rounded end-piece near where it is bolted onto the car - even when you are bending/squatting and trying to see it. You don't even really see the end-pieces if the sun isn't shining directly onto them. That bright red can really catch the sun though.

I really noticed the handling/performance difference with it on the car today during my commute. The car stays flat as a pancake on spirited turns or taking those curvy "40 mph speed limit" highway on/off ramps at higher speeds. I also didn't feel the wind pressure buffet the car like it used to when big-rigs passed right next to me at high speeds on the highway. It really is the best bang-for-the buck stability mod that you can make to a small, featherweight car like this.

Those are the wrong size bolts. The thread pitch is wrong. If you want to keep the dampers you need M10-1.25X30mm bolts. In US I purchased from Fastenal, I 'm sure they're available somewhere in Europe but I don't know where.

Yep, the bolts supplied with the TRD sway bar won't work if you plan to keep the dampers on your 2012-2014 3rd Gen.

Will this work?

They will. The only difference is the coating. Yellow zinc stands up to corrosion a little better than plain zinc coating. I went with the yellow zinc for that reason. FYI the bolts supplied with the TRD bar are yellow zinc coated as well.

Oh nice nice! I'll go with the yellow zinc ones then thank you!!!

I am so glad that I came across this post. I sold my 2009 Yaris about 3 years ago which I installed the TRD rear sway bar on. I am buying a 2012 Yaris SE this weekend and I plan on getting another TRD sway bar ASAP. This is the number one mod that everyone should do to the Yaris.

Now I know that I will need to buy new longer bolts to make the TRD sway bar fit properly. Did you remove anything from the car, or did buying the longer bolts allow you to keep the dampers in place?

I am going to have to take a look at these dampers when I get my car. I am really curious what purpose they serve and why they took them off after 2014.

Only thing removed was the original bolts holding the dampers in place. The dampers themselves have to be temporarily removed while fitting the sway bar. After you have it lined up simply reinstall the dampers in their original position and secure with the new longer bolts. Torque to spec. Done.

I have a mini DIY posted on the previous page that should answer any other questions.

Does anyone know if this bump stop would be reused with a set of tanabe sustec coil overs?

The coil overs should have its own bump stoppers.

I can't remember if there are bump stops with them. I'll have to look.

I just ordered a white line 22mm rear sway bar for my 2012. Does this issue still apply in my situation?

Just to be clear: These are not bump stops. They are just vibration dampeners to deal with NVH. Basically some chassis engineer found that in that area of the vehicle there was a vibration that may cause excess noise to the driver. So they bolt a dampener in place because it's cheaper than making new axle assemblies. Chances are you can remove the dampener and never notice any noise difference.

That's interesting. I have wondered about their purpose since I discovered them. So is this the "official" explanation? If so how did you come by this info?
