What I want to know/confirm is that any 330 front caliper and rotor will mount to the Z4.

I see the following
calipers:

and rotors:

on ebay and want to know if they will work.

I already have the M3 rear brakes (from when I did my M3 rear end swap), and the CSL/Porsche brakes are going to be a ways off (post engine swap). So it would be nice to pick up a little more braking capacity from the front without having to dump $2K on the CSL/Porsche setup right now.

You'll need the caliper mounts too - they are in the photo just make sure you get them.
