Caster tends to lean the car into a turn if it is set

Caster angle describes how far the steering axis is tilted from vertical in the fore-aft plane. When caster is negative, the upper pivot tilts toward the front of the car, which reduces trail and the self-centering effect. This makes the front wheels respond more readily to steering input and biases the front of the vehicle to steer into a turn. As a result, the car tends to lean into the corner more readily than with neutral or positive caster. Positive caster increases trail and stability, helping the wheel to return toward straight ahead, while zero caster provides little self-centering.
