This is per JABCAT DIY thread here: https://g87.bimmerpost.com/forums/sh...75&postcount=4

The rear bolt part # is 34-20-6-850-560.

The front caliper nuts are steel friction nuts, so are designed for single use (like Nyloc nuts, but they don’t work well on hot calipers), but the studs they tighten on to are not stretch fasteners, so there isn’t a jointing torque plus angle that would indicate the studs also would need replacement.

Fwiw - I reused all bolts/nuts. I have 9k mi on the car since the pad swap. No issues & everything is properly torqued. I also used a small flat head screw driver to pop the wear sensors off. They pop off with very little effort (at least on my two vehicles). But yes be careful with them.
