I was debating this with a friend. He thinks it would not matter. I looked all over the net for answers. Any mechanical engineers out there?
My thought is that a body is unsprung weight. You go over a bump and without suspension, the wheel takes more sudden shock. With suspension, the force of the body on the wheels is dampened and the sudden loads are diminished. Think of a hammer with a big piece of thick rubber separating the head from the bulk of the hammer. It would seem to make the hammer less able to pound a nail and a reduced sudden load.
