ASA AR1 20inch fitment question?

[BlackJetE90]

Gary,

I have a 2004 530i, non-sport.

Very interested in the ASA AR1 (Black) 20x9 fronts and 20x10.5 rears

What is the center bore measurement on the wheels?

What are the offsets front and back?

Thanks

[Gary@Tirerack]

These wheels are 74mm bore and use rings to make them hubcentric. 18mm offset up front and 26mm offset rear.
