I'm speaking with VMR directly-
their wheels can handle the weight of the e70 x5 and so I might make this purchase. They will bore out the wheels to match our hubs so it won't be a problem (for an added $100 fee). I'm just not sure if the offsets will work...
20 x 9 +35
20 x 10 + 35
I'm thinking it should work fine, and maybe add spacers to flush up the wheels to the body.
Take a look at my photoshop and let me know your thoughts- not sure why there aren't more VMR wheel owners here, since they are so popular with the 3 series crowd.
