One thing that I found quite strange about the IMSB is the centre stud.
I'm sure you have all figured this out many years ago and it's weakness has been mentioned on this thread already but I find it hard to believe that that stud (M8) is all that is supporting the rear end of the IMS which is driving the cams.
Well I know the bearing is but that is being supported by that stud/bush and the flange is fixing the stud to the engine ( which is very secure).
I suppose by increasing the diameter of the stud you have to decrease the thickness of the flange internal busing part as there is only the same amount of space inside the bearing.
