That is what I am saying. There is no interface between the bar and the chassis, there is no way for it to counter roll. Without some type of connection from the suspension to the chassis the bar can not do its job. All it does is stiffen up the rear beam, that is not what a swaybar does. This is a supplement for soft rear springs, nothing more. Put in the right spring and shock package and you can ditch that piece of steel.

I have only seen one attempt to build and install a proper rear swaybar (speedway style bar attached to the chassis and the axle) on a Yaris, and I think he ended up removing it.

But a lot of people like to believe it transforms the car... There are also a lot of people that think a front strut tower brace makes a huge difference. The front strut towers are inches away from the firewall, and the tops of the struts are mounted in 2" think rubber donuts, no way that bar does a thing. And then there are grounding kit fanbois. When it comes to bolt on accessories it seems like if someone will build it, someone will buy it.
