How to setup: Anti-Roll Bars

When your car turns through a corner, the anti-roll bars twist and resist the body roll, transferring some of the weight from the outside wheels to the inside wheels. This helps to keep the car more level and maintain maximum tyre contact with the road surface, improving handling and traction.
Anti-roll bars can be adjusted to change the stiffness of the car, which allows you to fine-tune the handling characteristics to suit different track conditions and your driving style.

When setting up the anti-roll bars you can increase their stiffness, or soften them up.
Stiffer anti-roll bars have the effect that the car will lean less in turns, which causes the car to shift its weight more progressively and makes it more stable.
Softer anti-roll bars will have the opposite effect, letting the weight shift around more, allowing for increased body roll and potentially some oversteer.

A common misconception about the anti roll bars is that stiffer is better, which is not true in most cases.
A rule of thumb you can work with is that softer most often means more grip, which goes for the anti-roll bars, the springs, tyre pressures and so on.
Beware that in the case of anti-roll bars, setting them too soft can cause a little oversteer.

We have a front and a rear Anti-roll bar to tinker with, and these have the following effects:

The front ARB mostly impacts the behaviour of your car on corner entry, and the rear ARB mostly impact the behaviour of your car when you get on the throttle out of a corner.
Before changing anything we’ve gotta have a goal in mind when making setup changes, and this is of great importance when we’re changing the ARB values around.
So if we’re having trouble on corner entry, we would want to change your front anti-roll bar.
In case of understeer, soften it up a little bit.
In case of oversteer on corner entry, stiffen it up a tad.

If the opposite is the case and we’re having trouble on corner exits.
We can soften our rear ARB if we’re struggling with oversteer.
And stiffen it up if we’re dealing with understeer.
