I didnt need any spacers for these staggered E70 wheels, only rings up front. No rubbing in rear.

Odd, all E70 wheels are CB=74.1. On an E53 (CB=72.6) they should require rings on all four corners. If rings are only needed on the front then the wheels came off an E71 which has rear CB=72.6. I have a pair of style 212s off the rear of an E71, lower offset and concave face, I needed adapters to run them on my E70.
