What Does a Stiffer Sway Bar Do

The stiffer the sway bar, the more resistance is extended to counteract the body roll. Too much sway bar stiffness creates excess pressure on the outside loaded tire causing a loss of traction.

Is a stiffer sway bar better?

Stiffer sway bars are not always better. While increasing the stiffness of the rear sway bar in a front wheel drive car might reduce understeer, an overly stiff rear sway bar can actually induce oversteer and make the car difficult to drive.

Are stiff sway bars good for drifting?

Sway Bars The rear sway bar is mostly used to help control side bite, and a stiffer car will actually reduce the grip, which makes it easier to initiate and maintain a drift but can lead to a less-predictable transition.
