Yes...the e70 X5M (only) and the e71 X6 models have different center bores in regards to the front axle vs the rear axle. Again, the split axle different center bore ONLY APPLIES to the e70 X5M...the other e70 models have the same 74.1mm center bore on front & rear axles.
This is why one should always check the BMW part nbr and specs on wheels since some platforms have models that have slightly different set-ups. Aftermarket wheels for the X5/X6 may use the larger center bore...and the front is adapted by using hub centric rings. If buying used X5/X6 wheels...then check their part nbr to make sure that you're receiving the correct rear wheel for your model.
The wheel spec list above hasn't been updated yet...but some of the new M models (like the f06/f12/f13 M6) has a different rear wheel offset range than the regular 6 series models of its generation.
