This suggests that just maybe assembly techniques have something to do with the misalignment, too.if it was only about misalignment, we would all see the same failure intervals, yet we don't.

The issue of full spline engagement is on the 6 speed transmission only.
I'm speculating that the oilhead clutch housing is structurally weak and easily deformed - so much so that even if the two alignment pins are in place, spline alignment isn't assured. The clutch housing is a thin aluminum alloy die casting and has a major cutout for the starter.There are 2 locating hollow dowel pins that align the transmission to the engine. The assembly technique has no options.
There are no springs needed because the cushion is achieved on the input shaft inside of both the 5 and 6 speed transmission.
A quick look at the appropriate parts fiche will confirm this.

Besides - there is much more torsional compliance (which is good) in the gearbox spring system than there is in the alternate clutch disk model.I checked the drawing. It does look like there is a spring right inside the housing on the 5 speed M93-M94 transmissions. I assume that does the trick. That, and the comment by Bikerfish that they aren't recommended means I will be getting the stock disc, if needed. Good. I usually prefer stock components, and in this case they are in fact cheaper. Interesting that RBS is another aftermarket company/repair shop touting the fact that they know more than the BMW engineers, and that we are fools to buy the German designed stuff.
