CAMBER

Normally, the angle of the bolt that passes through the C bend and connects the kingpin (i.e. the tire) to the chassis is adjusted by way of eccentric washers (washers with an off-set hole). Usually there are two of them, one on the top side of the C and one on the bottom, to allow for a broader range of camber adjustment and to keep camber modifications independent of other set-up factors. In fact, if there were only one eccentric bush, adjusting the camber would require us to also re-set the caster, the other key angle that defines tire alignment (see the next section).
