To be honest, I have not had the time to try and fit this on a E70. I kind of went with the facts posted here and on what saphireblack said as he is the only one who has retrofitted this exact wheel to his E70.

Maybe a call to folks at tirerack can solve this issue. If spacers are needed, I would only trust H&R spacers that come with lugs especially with such a heavy wheel.
