I just bought a set of CF tires...

Seriously, how much of a reduction in the moment of inertia of the driveshaft are we talking about by going CF and what is the significance of that in relation to the moment of inertia of the other rotating masses? I am pretty sure the M3 has a hollow shaft and they've done whatever they could have to keep "I" of the crankshaft low. Lighter wheels seem like a more obvious target to me rather than the shaft.
