On the knock-offs I would think you wouldn't be able to tell if they actually improve anything or are simply for looks. If you are going for a cheap upgrade to style then maybe they are worth it. If you are looking for actual improvements in handling then I wouldn't risk it (least for the uppers, where a good set can actually dial in more positive caster, plus improved camber curves).
