Hi all, I’m sorry for reviving this old thread, but I’m also trying to install m437 wheels on my Z.

There’s only one thing I don’t understand. As far as I am aware the m437 wheels are designed for 14mm bolts but the Z4 has 12mm. They both have a PCD of 120mm x5.

Are you using some kind of stud conversion kit to account for the difference?
