And I'll remind everyone that it's 22lbs of unsprung and rotational mass too. Somewhere it said that one pound of unsprung weight is worth six pounds of sprung weight, or something like that.

Some of the Z4 M owners have replaced the stock wheels with CSL wheels (and also the Continentals with PS2s). It is reported to have made a world of difference in response and drivability. It's worth it.
