Figure 10. Definition of Vehicle Heading. The steering angle is defined as the angle between the front of the vehicle and the steered wheel direction as shown in Figure 11. The steering system has a maximum (minimum) steering angle of +0.52359878 (-0.52359878) radians or +30 (-30) degree. Figure 11.
Excessive caster angle will make the steering heavier and less responsive, although in racing large caster angles are used for improving camber gain in cornering. Caster angles over 7 degrees with radial tires are common. Power steering is usually necessary to overcome the jacking effect from the high caster angle.
