Anti-Roll Bars or Sway Bars
The first and one of the simplest modification for your car suspension is installing anti-roll bars or sway bars. An anti-roll bar is essentially a lever connecting two opposite wheels. When cornering, the outside wheel and suspension are under much higher pressure than the inside wheel. This results in a roll. Anti-roll bar, which connects two front wheels or two back wheels, is under tension when cornering which directly affects the wheels. This tension results in the anti-roll bar lifting the inside wheel thus reducing roll and effectively leveling car corners.
To put into perspective what an anti-roll bar can do, just think of all those cars that roll a bit too much when cornering hard. They sport soft anti-roll bars. Stiffer anti-roll bars will have a greater effect on reducing roll. The car will feel more precise through bends. Moreover, less roll will help tires maintain ideal contact with the surface.
