I was wondering if anyone knows of a document, or website, that shows which BMW Factory wheels will fit on other BMW models. For example, the E30 wheels that fit on the 2002 and the E38 M parallels that fit on the E34 M5 etc. I know some others will fit with hub centric rings and some will fit with with wheel spacers as well. I would have found this very useful when I was looking for winter wheel options. Thanks in advance.
