Adjustable cambers??
All of these settings affect the angle of the wheel relative to the longitudenal and vertical axes of the car. Here's a link showing the basics of caster, camber and toe. They can be measured in terms of degrees of offset from one of the planes or in terms of fractions of inches of offset.
Toe is the angle of the wheel relative to the running direction of the car. Imagine a bird's eye view of the car - when toe is 0, the tires are exactly parallel to the longitudenal axis of the car. Most cars run with a little toe-in. This gives stability, but if toe-in is too high, the tires will scrub and wear more quickly than desireable.
Camber is best visualized from a front or rear-on view of the car. When camber is 0, the tires are exactly perpendicular to the ground. Most performance cars run some amount of negative camber. When running in a straight line, that puts extra pressure on the inner part of the tread, but improves grip by making the tire run flatter in turns.
Caster angle is the hardest to visualize in a car, it is basically the angle of the steering pivot to a vertical line. Caster imparts a centering force on the wheel when the wheel is turned. When coming out of a turn, if you let go of the steering wheel (not recommended!), the front wheels will point straight ahead.
