A set of winter wheels I bought for my E70 came off a E53 4.6is which for some reason had 72.6mm front and 74.1 rear center bores.
To install the front I ordered a set of H&R adapter/spacer all in one along with longer wheel bolts. The adapter is 72.6mm on the wheel side and 74.1mm on the hub side so I easily mounted the front wheels.
