If you can find a set you can put a set of Z3M wheels on a 1.9 if you are changing the rear wings and sills.

Its the offset you need to consider rather than just the rim width.

Sizes of M alloys and offset range

Very wide, depending on offset but even at that, very wide wheels indeed.

17s or 18s?
