CASTER

In theory, what holds for the camber also holds for the caster. You can adjust either angle by shifting the eccentrics, or similar components, that control the tilt angle of the bolt that connects the spindle pins (and therefore the tires) to the C bends of the chassis. Just like with the camber, fitting the C bends with two eccentrics each, one above and one below, offers a wider adjustment range for each angle and, more importantly, allows to adjust each one independently of the other.
