Wheel spacers on BMW X7

Question

I would like to mount a wheel spacer on my X7. The rims should close nicely with the fender. Unfortunately I have not yet found any information on this.

As summer rims I have the original 755 M 22"

Has any of you already installed track plates? If so, what fits in front and back?

Answer 1

I have had them in the garage for 4 months. The problem is that the suppliers like SCC are unable to produce a parts certificate. Therefore I have not been able to assemble them until now

Answer 2

I learned from a forum that 15mm per side and 12.5mm per side fits very well! I can not say whether a little more is possible! I think I'll order them for the back...
