Excessive body roll is a performance car’s enemy. To combat this, we need various components to tune your car’s suspension.

One of these components is the sway bar or, perhaps more formally, anti-roll bar. It helps reduce the body roll of a vehicle during fast cornering or over road irregularities. It connects opposite (left/right) wheels through short lever arms linked by a torsion spring. A sway bar increases the suspension's roll stiffness—its resistance to roll in turns, independent of its spring rate in the vertical direction.

Meanwhile, body roll happens when you turn into a corner. As your car begins to turn, its weight is thrown to the outside of the corner, causing your car to roll in that direction.

Simply put, a sway bar is a metal crossbar that ties the driver and passenger side chassis and suspension together. You will feel its effects as soon as you crank on the steering wheel and enter a corner, a sway bar ‘springs’ to life to help control the weight shift that occurs during cornering.
