A Search would have turned up the wheel site below:
http://felgenkatalog.auto-treff.com/
Click on "Alle" drop down menu and take a look at any/all of
the E53 wheels: there are many styles with offset right in
the 40s. Whether your specific aftermkt wheels will fit is
not known by me. But, the offset is in the ballpark.
Many prefer a staggered look in 19"/20", but diff'n strokes.
