I did this, and ended up putting the stock aluminum mids back in the doors..... kept the bav tweeters, as they were an upgrade over stock. I felt the mids were a lateral move. I preferred the sound slightly with the original mids. Now, this is based off the premium system, which I think you have since you also own an "M". An older Z4 with the non Carver 10 speaker system would most likely benefit from the Bav Sound upgrade. YMMV
