Actual hub measurements are what you have listed.

In order for wheel to "fit" over the hub, the measure needs to be slightly larger:

I found 74.1mm and 72.56mm for the actual bore measurements.

Make sense?

Look at this link for X5 e70 replicas. Look down on right under measurements and the bore opening measurement is 74.1. This would allow proper fitment "over" a 74.0mm hub.

Ok. Let know when yours is done. Its interesting that most BMWs except E39, E70 and E71 have 72.5 mm bore.

I wonder why BMW uses these different bore sizes for almost like vehicles...

could be a marketing strategy more than an engineering one.

I will definitely follow up the day I pick them up. I will mount and take photos of fronts and rears together. I will "test drive" and let you know

I posted these on another thread but I can't find it any more lol

I picked up a set of the same rims for my E70 and had the rear bored out just a few weeks ago:
