Lesser extent is an understatement. Less than 1% vs. 8-10%. There are many motors from many manufactures that have engine failures near 1%. And as for the argument that the more bearings mean more metal particles in your oil, not so much. If your double bearing is shearing off slivers of metal, it will totally fail at some point so I don't think this a big issue due to the less than 1% failure. With the current stats that Porsche has released, I think if you have a double bearing engine, you can rest easy! The double bearing engines are no more likely to have total engine failure than any other performance motor. I'll think about changing mine when I need a new clutch. Until then, I'm not going to give my IMS a second thought!:dance:
