I'm pretty sure that the IMS bearing revolves at crankshaft speed (up to 7,200rpm), so some of our more qualified members might like to comment on this new style of bearing.....

That said, I'd just as soon not have anything but a shell bearing in there, and now that there's an option for that.....
