Most of the suspension/alignment measurement that people talk about relates to the angle of the wheel and how relates to the centerline of the car, laterally. Examples:
-Toe: the lateral distance between the front end and rear end of the wheel/tire, can be expressed as an angle
-Camber: the lateral distance between the top end and bottom end of the wheel/tire, can be expressed as an angle
-Caster: imputed from camber gain across a sweep of steering angle, which are both lateral measurements.
-Track Width & Thrust Angle: Lateral distance between the wheels, and the lateral difference between the front and rear track width, expressed as an angle.
What these measurements don’t consider:
-fore, aft change in suspension components across the vertical movement of suspension (compression from full droop travel)
So, to capture some of this, we plot the actual change of pickup points and references points of suspension with vertical lasers like this:
