Echo all above (CDV, cutch stop, trans mounts, etc.)
A high grade trans fluid is reported to help as well.

The mods mentioned above are inexpensive and vital, in my opinion, to smooth shifting. I smiled ruefully when I recalled the jack-rabbiting and bunny-hopping that was common for me before I made the changes. Yes, both you and your passengers will wonder if you even know how to drive a stick until you address these things. This is probably the single major quirk of the Z4M.

Also, experiment with the RPM for the sweet spot for 1-2 shifts. Unless you are short shifting (gently) to play with 2nd gear torque, you might find that the 1-2 shift happens more smoothly at a higher RPM than you are used to. This was my experience and I usually hold off until I'm above 5000 and even above 6000 for the smoothest shifts. Then engine seems to enjoy it too.
