In an ideal world, all wheel alignments would be done on a dynamic wheel aligner but these are expensive and quite rare. This concept is very important, as the only suspension angles that really matter are those present while the vehicle is moving (dynamic). What is done to the vehicle's alignment while the vehicle is stationary, (static) is a process of trying to predict the levels of change while the vehicle is moving and setting the angles according to these predictions.

Static negative camber is used to compensate for body roll, body distortion and tyre roll under when cornering. Stiffer bodies and tyre sidewalls are in and unnecessary suspension compliance is out. Therefore the previous requirements for large amounts of static negative camber are disappearing. Whiteline strut braces are good for maintaining camber angles under cornering loads as they further minimise body flex.

What Caster Is:

Caster is the backward or forward tilt of the steering axis. Vehicle manufacturers are aware of the advantages of caster and as each new model is released the amount of caster specified increases.
