To answer your first point, Powerlex are not trying to reinvent the wheel. They are just substituting a different material to do the same job. Secondly, don't think Alfa as all manufacturers get it right with all their development and money they still get it wrong. This is why there are so many recalls. Have a look at the Alfa Workshop site to see the kit Jamie has developed to improve the 4Cs handling. Having spent a superb day courtesy of Alfa Romeo driving both the coupe and convertible 4C, I can't say i noticed anything amiss but regular drivers of car clearly do and have apparently made a better job than the Alfa engineers did. However, I digress, I don't think there is anything wrong with the standard suspension set up on the 916, the Powerflex just replicates it.
As for longevity, the example you cite really is rare. There are so many instances of worn oe bushes. Otherwise why are people bothering to change suspension parts? On top of that, have you seen the damage that worn oe bushes do to the alloy subframe? They grind the metal away meaning the whole subframe has to be replaced. That's ok at the moment ( well, I say ok, it's still an expensive job) with second hand subframes on the market but when they are gone...... As an engineer, I would much rather replace a split Powerflex bush then the whole subframe.
Finally let me reiterate, I'm not against oe and I'm not pro Powerflex, I'm just saying that from all the feedback from people who are running Powerflex, 90% plus notice no detrimental effects to the handling, usually they think it's improved.
