Swaybars are a useful tool that can be used to change the balance of the car, and are used to adjust the carÌ¥s lateral grip. The basic setup for the Yellow Edition is 2.4 front, 2.5 rear. Thicker swaybars are used on high grip tracks, specially if they are high speed also. Normally a larger difference than 0.1mm between front and rear swaybars is not used, the rear is either 0.1mm thicker, or both are the same. For less steering, and a more stable car, increase the thickness of the front swaybar.
