Objective Ok, that's enough laughing. And without positive caster and the resulting self-aligning torque, the vehicle would be very inclined to wander at highway speeds. An except from advanced racing: Caster is the angle to which the steering pivot axis is tilted forward or rearward from vertical, as viewed from the side. What's the downside to positive caster? This is a great way to maximize stability since it creates a pulling effect inward on each side of the vehicle. THE EFFECTS OF CASTER .

A positive caster angle produces a self-centering action of steering, and gives a steering feedback for the driver in straight line. Negative caster is found only in older vehicles as it is a limitation of older technology such as outdated chassis dynamics and tire specifications. Thrust Angle. Once the caster is adjusted to your liking, check the camber, toe, and ride height again and make necessary adjustments to ensure that all measurements are within spec for the vehicle. The steering axis of a shopping cart wheel is set forward of where the wheel contacts the ground. That is the power of caster. Self-aligning torque happens when the lower pivot point is farther forward than the upper pivot point and the force is then applied to the front wheels to make the wheels want to return to their neutral position in a turn.
