I still have a very hard time believing a conventional manual transmission for the B58 in an F20/22/30 weighs 225+ lbs (192 for 8HP, plus 35 difference). A T56 barely weighs half that and certainly has more capacity than either GS6xxx manuals (Getrag or ZF) in the BMW...

Agreed. The manual is normally lighter, and I was just as surprised, so it could be a typo, but then I read this:

According to Quintus, BMW M can develop manual transmissions to handle the torque but the extra strengthening makes them heavier than an automatic and the shift quality becomes quite poor.
