What is the difference between camber and caster?
Caster is the angle between the verticle line and kingpin centre line in the plane of the wheel when the viewed from the side is called the caster angle. Camber is the angle between the centre line of the tyre and vertical line viewed from the front of the vehicle is known as the camber angle.
How do you read camber specs?
The camber angle is read one degree plus or minus 30 minutes. The ( ‘ ) or minutes symbol is used to view or represent angles just like an actual clock. The thirty minutes reading equals one half a degree. Notice the 45’ or forty-five minute reading for the RF.
Do you set caster or camber first?

Do you want positive or negative caster?
Caster is said to be positive if the line slopes towards the rear of the vehicle at the top, and negative if the line slopes towards the front. Increasing the amount of positive caster will increase steering effort and straight line tracking, as well as improve high speed stability and cornering effectiveness.
How much positive caster is too much?
Vehicles with too much positive caster can be prone to understeer, so most modern vehicles don’t have a caster greater than 3 to 5 degrees. This is the ideal range to maximize straight line stability and still allow for comfortable turning.
Can Caster cause a vehicle to pull?
Poor camber and caster alignment can cause your vehicle to “pull”, and can cause tire tread to wear unevenly. It is no different on four wheel vehicles. If you don’t have enough positive caster (forks too little angle toward the front) the car will wander and feel unstable.
