Coming from Usukani or their PDSR series drift cars is this active toe system. Consisting of new rear aluminium uprights, which has a ball raced pivot point at the base, as well as a system to attach the upright to the arms, the active part comes from a track rod mounted between the lower arm and the upright. Featuring a multitude of mounting points for fine adjustment, as the suspension travels up or down the small track rod pivots the upright from its default position. How much that moves depends on the attachment point of the link. The set comes with everything required to complete the conversion of the left and right of the car.
