The idea of an anti-roll bar is to reduce body roll as the car corners independently and without significantly affecting the stiffness (rates) of the suspension springs. Fitting them to road cars allows spring and damper rates to be soft enough for comfort while keeping body roll in check.
Is anti-roll bar necessary?
But the anti-roll bar has another super important role – it acts as a second spring to add spring stiffness at the tyre, but only in cornering. If we go too stiff with the springs, grip at the tyres for braking and acceleration will be adversely affected.
What happens if anti-roll bar breaks?
If the bar is broken, you may notice a difference in the car’s steering and cornering may become more difficult. This could particularly pose a risk when driving at high speeds, which is why it’s important to keep a check on your anti-roll bar and get the car suspension system serviced regularly.
Do anti-roll bars make a difference?
So, without reducing comfort or articulation, an anti-roll bar will make the suspension system and tyres perform better, making the vehicle more responsive while neutralising understeer. Fitting an anti-roll bar offers all round improvements in handling, tyre wear, comfort, safety and load carrying.

Are sway bars worth it?
Sway bars improve a car’s handling around turns and corners by controlling the vehicle’s weight transfer, including body roll. By working to keep the wheels on each side of the car as even as possible, they help keep the car more planted and maintain a strong contact patch between the tires and the ground.
Do sway bars need to be replaced?
Checking Sway Bar Links / Bushings
