However, the Powerflex website does not show an E53 fitment. Both the E39 and E34 front suspensions are different than the E39 - control arms don't look the same. I wonder if this is a mistake in the Evosport catalog.

Certain control arm bushings tend to bind up if they are polyu depending on their movement angle. Also, polyu bushings
do require somewhat regular lubrication. They do have their advantag, but require their share of maintenance.
