Excess positive caster will require extra steering effort. Excessive negative camber? This takes the … Camber angle is one of the angles made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of a wheel and the vertical axis of the vehicle when viewed from the front or rear. Each of these affects the others, so changing one of the angles should be followed by re-measuring the others and checking the suspension components. Toe refers to the point of the front tires when the car is viewed from above. The benefit of this angle is for making turns around corners because the wheels and tires are positioned better for this purpose. Excessive negative camber will cause accelerated wear on the inside edge of a tire. Excessive positive camber will be exhibited by excessive wear on the outer edge of the tread due to the excessive outward lean of the upper edge of the tire. You can see this because the tire overall looks good without much feathering until right on the inner edge. Excessive camber either way will cause excessive and abnormal tire wear. Caster.
