6-series ACS type IV on X5 4.4 does not work

[steelgray]

Thanks again legion, you probably saved from a possible severe mistake
See answer from AC Schnitzer rep. below: (I am on the hunt again)

Dear Mr.

Thank you for your inquiry- We agree that your thoughts are right but must inform you that the front wheel does not fit as you would have to use the front wheel of the M5.

But worse is the following problem.

The wheel load of the M5 and 6 series wheels is 50 kg less on each wheel than the needed load for the X5. Thus a breaking of the wheels installed on X5 can be possible.

We are sorry not to be able to give you more positive comments.

Best regards

Just proves that it was well worth asking the question when it comes to the safety implications of a modification.

I think it also underlines the fact that just because a part fits or its OEM or approved doesnt mean its compatible to the X.

Good luck with the search.

So:
For a 645i -
9.0J X 20.0" ET 15 Front with 7mm spacer = 8mm total offset
10.0J X 20.0" ET 13 Rear with 20mm spacer = -7mm total offset

For an X5 -
9.0J X 20.0" ET 35 Front with 7mm spacer = 28mm total offset
10.0J X 20.0" ET 23 Rear with 10mm spacer = 13mm total offset

If i skip the recommended 645 spacers i end up with:
Front 15mm offset (compared to rec. X5 total offset of 28)
Rear 13mm offset (compared to rec. X5 total offset of13)

So, rear is perfect, front will protrude 13 mm more than recommended.
Right ?
Or am I missing something??
Will 13 mm be to "fat" in front?
Or will it look strange compared to the rear?

You're right, I reversed the calculations.
