Editing Anti-roll bar (section)

=== Main functions ===
Anti-roll bars provide two main functions. The first is to reduce body lean. This is dependent on the total roll stiffness of the vehicle. Increasing this stiffness does not change the steady state total load (weight) transfer from the inside wheels to the outside, it only reduces body lean. The total lateral load transfer is determined by the center of gravity height and track width.

The other function of anti-roll bars is to tune the handling balance of a car. [[Understeer]] or [[oversteer]] can be reduced by changing the proportion of the total roll stiffness that comes from the front and rear axles. Increasing it at the front increases the proportion of the total load transfer that the front axle reacts to—and decreases it in the rear. In general, this makes the outer front wheel run at a comparatively higher slip angle, and the outer rear wheel to run at a comparatively lower slip angle, increasing understeer. Increasing the proportion of roll stiffness at the rear axle has the opposite effect, decreasing understeer.
