I would buy a set.
I installed poly bushings in the stock ones and IMO it made no difference. Well other then the fact the bushings will never rot away.
The stock control arms are just too structurally weak to notice any difference in bushing material. I even added a few more insulators to help to no avail.
I was already planning to remove them (when it's warmer
) and fill them with 94A urethane casting compound (I.E. soft rock
) like I did the front control arms & roll resistors.
