//M contours- what is the offset and how will they fit on my E30?

[Roysneon]

I'm picking up a set of //M contours at a decent price for another set of wheels for my project car once the E30M3 suspension swap (and everything else) is done and I have some questions.

From my research the offset is 41mm? So I'd need spacers for the E30M suspension? Also, that would allow me to use adapters to run them on my other 4 lug car in the mean time without having poor final offset, correct?

Offset is correct.
Will need spacers for a proper fitment. 15mm to 20mm spacers would be sufficient.
Go with 18mm to 20mm thick adapter to make them work on a 4 lug hub.
