What is Caster?
The longitudinal inclination angle of the vehicle’s wheel turning axis.
Castor is measured in degrees and is the angle in the longitudinal plane of the vehicle between the vertical line and the line passing through the wheel turning centers.
This line passes through the ball joints of the upper and lower suspension arms («classic» double wishbone suspension), or through the upper and lower shock absorber strut mounting points (MacPherson suspension), or along the kingpin axis (kingpin suspension) in the longitudinal plane of the vehicle. Castor can be either positive or negative.
What do we do?
We install a special shim on your track between the beam and the spring. Depending on the size of the shim, the angle of your caster changes and thus we neutralize the track drift to the side.
