I have PBM suspension arms on my other subframe and I think these are great if your car is really low. I mean really low. The newer ones have the ability to lock in alignment specs without slip so that's definitely a plus.

The cons of PBM arm (and maybe all suspension arms with spherical bearings) are that they aren't really daily driver friendly. At least, for me they aren't. Some people can and probably will not mind them but I like being comfortable in my daily driver. Some don't mind it.

With suspension arms, you really get what you pay for. Ebay arms typically have terrible bearings and bad welds along with low quality metal. They really should only be used for shells that roll around.
