I can't speak for his wheels, but I'm running 17x9 et30 Apex ARC 8's with 255/40/17 R615k+ on my m3. Fitment is...challenging. I'm maxed out on negative camber in the front at about -2.5 deg (still need to get a real alignment). I also have to run a 10mm spacer at the minimum to clear the wilwood calipers I've got.
The rear rubs much worse. I'm running about -1.5 deg negative camber and no spacer and it still rubs over bumps. I'm waiting on my fender roller to come in the mail to try to adjust it.
In the mean time, I raised the car up slightly on all 4 corners and firmed up the damping a bit (I'm also running TCKline single adjustables-450# front and 500# rear)
so yeah, it's definitely not a plug and play fitment, but it should work with a few tweaks. Plus, it looks great and the grip is phenomenal. Granted, part of that comes from getting rid of the 12 year old Pilot Super Sports I had before. Here's a low quality picture of them on my car
