Here are pictures of my 2017 M240xi on a drag pack. Going to be switching out the fronts, but for now this is the setup.
Stock suspension! Just 17x10 +42 (don't quote me, but it is in the 40s) weld drag packs on Mickey Thompsons 275/40/17s R and 245/40/18s fronts.
Enjoy!

(*No rubbing/issues with this setup, so far)
