GP Racing has introduced an interesting “traction bar” system in their latest chassis. The purpose of the system seems to be to adjust the stiffness of the waist of the chassis. The genius behind the system is its adjust-ability on the track similar to adjustable anti-roll bars in some race cars. You could start a race with the bars “stiff” and then adjust to “soft” as the race goes on. Pictures below by WafeProject.
