For those who don't know what a Sway bar is, here is a brief description. A sway bar is used to help prevent the car from rolling (swaying) around turns, which in turn helps the car hug the road better. The theory behind them is pretty simple.
The sway bar (in the pictures on the right, it is the white rod) is attached to the A-arms, and to the chassis (or bumper in this case). Going over bumps with both tires does not use the sway bar much at all (other than to stiffen the suspension) since the sway bar hinges on both the A-Arms and the chassis/bumper, but going over a bump with only one tire compresses that side of the suspension, which tries to "twist" the sway bar. The sway bar tries to resist the twisting (or torsion), by pushing up on the other side of the suspension, thereby compressing it. So as one side of the suspension is compressed by a turn, the other side will be as well, make the car squat down around turns.
After adding this quick and inexpensive mod to my car, I was able to take corners at nearly full speed, with very little sliding or rolling.
