I have found a set of wheels I'd like to purchase for winter use. I will be putting them on a 2012 35D with the Sport Activity Pack (ZAP), with the 20" wheels w ZSP only (2LE).

The summer wheels measure 10Jx20 ET:40 (F) and 11Jx20 ET:37 (R)

I am interested in the wheels mentioned in this post. http://www.xoutpost.com/bmw-sav-foru...10-2011-a.html
Post #4 from LeMans X5 states the rear wheel bore size is incorrect, will this adapter work? Home Page > Search > ES1895165 > ES#1928282 Hub Centric Ring Adapter Set - 747260

Now I am left with a question regarding the offset of the wheels, both wheels measure 9x19.
Part # 36-11-6-785-503 (f) has an ET of 37 and, part # 36-11-6-785-504 (r) has an ET 0f 18.
Will the ET 18 make the wheels stick out to far on the rear? Would it be better to go with the ET 37 on all four corners?

Does any one have pictures of 9x19 ET 37 or 9x19 ET 18 on the rear of their X5?
