I gave up looking for steelies for my 450i What is your bolt pattern 110/4 ?
I found that the 450i has the same bolt pattern (110/4) and wheel width and offset, as the original Datsun 240Z and started my search accordingly, I wasn't looking for steel, as much as 15" so that I could put street tires on, Found a set of relatively inexpensive aluminum(they were cheaper than the tires) wheels $350/4
