@ boxster:
Well, i think it's a common, human problem. If you ask 10 people you'll get 10 opinions.
Personally i respect all the 10 poeple for their knowledge, but than i do my own research, look for facts and try to form my own opinion.
First step is to understand why the Porsche OEM solution might fail. Than you should do a research what solutions are out there and why poeple think their solution is best, what maintenance is requested, are there any guaranties that are really can be callled guaranties. How often were the after market products sold, how often did they fail, or are there any other problems… and so on.
And than there is the time consuming part. Research for facts. Research on bearing types, reseach on high quality bearing manufacturers, coatings, quality levels, how to replace things best, research on engineering solutions for the problem. Talking with engine developers, engine engineers, mechanics.
All hard facts about the OEM bearings (dimensions, type, rpm) can be found in this forum.
In the end you might have your own opinion.
Maybe this is not the answer you have asked for, but this was my way after getting stucked besides an IMS bearing war - we also had that in the german Porsche forums.
Regards from Germany
