anti-roll bars are like "soft side": work only in transverse direction. The operating principle is as follows: when one side of the suspension is compressed, that extreme of the bar is raised. The other end of the bar will tend to rise, lifting the other side of the suspension, which turns into a resistance rolling chassis. How strong and how much, the other side is raised depends on the torsional stiffness and thickness of the bar: a long thin bar will twist, and do not raise much the other end, allowing the frame to tilt to the extent permitted by the suspension . Note that the bar is called for only when one end is at a different height than the other, as in the curve. When both ends are raised to the same extent as when braking, the bar is at rest and has no effect. For this, the anti-roll bars only affect the cross-flooding of the machine, not the longitudinal.
must be said that the anti-roll bar I'm not the only factor that determines the tendency to tilt the frame: they work together with the springs and shock absorbers. Suppose you use an anti-roll bar at the rear, without changing any other setting. When the car enters the curve, the chassis starts to lean. Normally, the outside suspension compresses, the inner and outer wheel would extend support a load much greater. With anti-roll bar, however, even the inner bearing is somewhat compressed, so the frame tilts less, and the rear end remains at less than normal. In this way, the rear end bears a greater load, and this is distributed more evenly between the two wheels, traction is increased and more consistent. Remember that this applies only to the inclusion in the curve, the mid-corner situation is different. Normally, without the anti-roll bar, the chassis tilts would stop when the outer spring has fully offset the torque roll. Instead, the anti-roll bar, a bit 'of that torque is compensated by the inner bearing, pressed by anti-roll bar. If the suspension is compressed outside less than normal, the rear floor has a height greater than normal, reducing the burden borne by increasing the rear and on the fore. And 'as if the rear had a bit stiff', increasing directionality and decreasing the traction at the rear. This, however, is more constant, since the weight is distributed evenly between the rear wheels. None of this is on rough terrain: the anti-roll bars can significantly complicate the behavior of off-road machine, and so are rarely used on rough tracks. Use an anti-roll bar on the fore similar but opposite effect: decrease the directionality, but making it more consistent and uniform.
