    C2 FRT END "CASTER" SETTING EFFECT

    Exactly how does the caster setting on the front end effect the way the car handles? (if it does)

    The more positive caster the more tendency to go straight. Increases centering forces. If it is unequal it will tend to pull to the side with less caster.

      How is setting the "caster" different than setting the "toe-in"with the tie rods?

        What is the difference between apples and oranges? Toe and caster are two completely different things. Positive Caster is the backwards leaning of the steering angle from the lower to the upper ball joint. Look at the front forks of a bicycle. Toe refers to the difference between the distance between the front and rear of the tire. Stand with your toes together and look at your feet.

          Rob, the spindle has an axis around which it rotates. This axis can be adjusted by changing the shims from either of the upper A-frame bolts but not both at the same time. The degree to which the actual rotational axis differs from the perpendicular axis is the caster angle. The caster angle creates a force/tendency for each wheel to return to the center position.

          I am not an expert but this is sort of how I understand it so far. Later, Terry

              Barry,

              Great article and description, I appreciate you taking the time to post it. It certainly explains front end alignment,

              Thanks Again, Rob

                I should have said,

                "...as viewed from the side of the car."
