(Above and below) Adjusting the rear radius bars can affect how the race cars responds during turning. As the car leans to one side in the turns, and the suspension is expanded to its limits on one side and compressed on the other side, the angle of these bars changes. This causes the rear end to simultaneously shift and create rear steer. In these two photos, the tape shows you how much the rear end shifts (arrows A) from its normal center point (arrows B).
