My thougth was that since there is a 1/16" gap between the rubber and the hanger on each side... That if cornering hard, the rubber could flex and the spring eye could move from side to side. If the rubber was touching the sides, there could still be side to side movement in the spring eye but it would be greatly reduced. It sound like this movement isn't enough to worry about. I had thought about adding a thin stainless washer on each side of the spring eye to take up the gap. The center hole in the washers would be large enough that the center sleeve would pass through them and still clamp tight to the hanger. Probably just over thinking it.
