See the first post in the linked thread...does not explain the example you are looking for, but read the wheel bore, offset, bolt thread & reach, for an idea.
Maybe another poster will know your specific fitment answer...that style 106 is off a Z4, not Z3. Not my fave wheel...if I was dying for 17s, I would look for style 57, et al, from an X5 or some 17" X3 wheel. Just my opin.
