I disagree. Just by tilting a coin back and forth along an axis diagonal to the table, the center of the coin - the president's nose (!), seeemed to move closer to the table the more extremely I rotated the coin. Rotating the coin along an axis of 45deg actually cause it to "flop" down as I rotated it from the vertical. In effect, this leads me to believe that both positive(desired) and negative caster have the effect of LOWERING the nose of a vehicle when excessive amonts of caster are selected(10 degrees or more!).
This is offset by SAI, which tends to RAISE the nose of the car as the front wheels are steered away from straight-ahead.
Can anyone visualize what I'm talking about in regards to the former (caster)?
