I just saw this and want to share with you guys about how sway bar work from wiki.
http://en.wikipedia.org/wiki/Sway_bar

The stiffness of an anti-roll bar is based on the fourth power of its radius, the stiffness of the material, the inverse of the length of the lever arms (i.e., the shorter the lever arm, the stiffer the bar), the geometry of the mounting points, and the rigidity of the bar's mounting points.

The stiffer the bar, the more force required to move the left and right wheels relative to each other. This increases the amount of force required to make the body roll.

I am not sure is the meaning of power of its radius means the thickness of the bar?
If so, I should have went for thicker version 23mm.

It says the fourth power of it's radius because the formula takes into account the bar's polar moment of inertia (J=(pi*d^4)/32) I believe.

Now I got it, thanks for the explaination. That makes 23mm version even more tempting lol.
