If you decide to pull out one of yr e91 wheelbolts to check if an F31 bolt will fit into the empty bolt hole, I'd be interested to know how it goes.
interesting, found this
looks like they should fit; the mounting cone contact area would appear to be the similar (or at least not smaller), and the angle looks the same.
you wonder why they changed the diameter & pitch though.
f31 is 40,000 miles away for me so not an immediate concern yet.....
