"""BMW""" wheel questions.

[LowBuckX]

I looked on Project supercarX web site and couldnt find what I need to know. Here is what I hope some one can answer for me.



1) what Is needed for a 5 on 120mm wheel to fit on a 5 on 4 3/4 bolt pattern?

2) Do you need a ring made to fit the hub center to the wheel?

3) What year and make BMW should I be wheel shopping for?

4) What is the back space on these rims. In inches not mm or how can I convert Offset in mm to backspace in inches?

Thanks. Ebay seems to be a good source for these wheels at a very nice price but I dont want to get something I cant use...

Thank you for the help.
