I can addd my own experience.

I have SuperPro poly bushes in the LCAs on my F31 330d which have worn considerably. They were identified as an MOT advisory and definitely need replacing. In short, the LCAs don't simply rotate in a radial plane (relative to the centre rod of the bushes), they also twist as the suspension compresses. This causes the hole through the poly material to become oval which then creates a significant amount of play in the system.

SuperPro have removed these bushes from sale and are developing an alternative. The trouble is, it's taking months. I'm having to do all the chasing via SuperPro's European distributor (there's no pro-active communication from them) and SuperPro Australia (HQ) is completely non-responsive.

I'm not impressed.
