OVERVIEW-CASTER
CASTER:
To understand caster, you need to picture an imaginary line that runs from the upper ball joint and extends through the
lower ball joint. From the side view, the imaginary line will tilt forward/backward. The tilting of this imaginary line is
defined as caster.
Caster is measured in degrees by using a caster camber gauge. If the imaginary line described above tilts towards the
back of the go-kart (at the top), then you will have positive caster. If the imaginary line tilts forward, then you would
have negative caster.
Positive caster provides the directional stability in your go-kart. Too much positive caster will make the steering effort
difficult. Power steering will allow you to run more positive caster. Negative caster requires less steering effort, but can
cause the car to wander down the straightaway. J&J go-karts only provide for positive caster.
Karts with single-wheel-drive are set stock at the second hole, which is approximately 4.7 degrees; two-wheel-drive
karts are set stock at the third hole, which is approximately 9.2 degree caster.

Caster is the inclination of the steering axis from vertical in the longitudinal plane
(wheel viewed from the side). Positive caster is achieved when the steering axis is
inclined toward the rear of the vehicle at the top in the side view. Negative caster
is when the steering axis is inclined toward the front of the vehicle at the top in the
side view.
