15degrees is to much. Any steering corection will X the traction to the outside
drive wheel and and cause badness,even morso when you correct! Caster is for
letting go of the wheel in a turn causing it to center. You have a steering
wheel to do that! Yes it does contribute at the onset! As soon as traction
fails and the car moves sidways ,the driver corrects, and caster causes
trouble. Elininate it! You control the car, the car shouldn't control you! Jack
