Well they're not rubber bushes anyway, the short control arm outer and long arm inner bush seem to be a metal pivot with protective rubber boots. As they don't flex, just rotate and pivot about, I don't see how a polybush is going to make things any better, assuming there's no play in them. Would have thought any flexing bush (poly or rubber) would be worse as the control arms could then change length under load. Perhaps someone could explain?
