Stabilizer Bar / Sway Bar / Anti Roll Bar

You can call it what you like... Stabilizer, sway or anti roll bar... The purpose of the stabilizer/sway/anti roll bar is to tie the left and right wheels, either front or rear together to help control bodyroll... For example, as an RC car rolls through a left hand turn, inertia forces the car to roll over it on the right side... If there is no sway bar, the right side suspension compresses and the left side goes into droop or extends... With an on road car like touring and drifters, this overloads the right side wheel and under utilizes the left and in tun lowering the car overall ability to maintain traction...


Let's add a sway bar to the scenario... As the car rolls through the turn, the right side of the suspension compresses as before... But now instead of the left side of the suspension going into droop, the sway bar pulls the left wheels up... This limits body roll and actually causes the car to settle down through a turn... The end result is actually to lower the car's center of gravity thus making it more stable...

Just like spring for absorber, sway bar comes with soft, medium and hard... So it is important to choose it according to your driving style and also track condition... If you are driving on a high traction surface and your car wants to oversteer, try to use sway bar on the front only... This will decrease the front chassis roll and decrease steering throughout the corner... This has the feeling of increasing rear traction... If your car is understeering, then try using sway bar on the rear only... The rear sway bar will decrease rear chassis roll and decrease rear traction... This has the feeling of increasing steering... If the conditions are very bumpy, then sway bar are not necessary... That's because if you hit a bump with one wheel, a hard sway bar can also upset the wheel on the other side of the suspension... This can cause smaller bumps that are not a problem with a plush suspension to feel much larger than actually are...
