Some pics of the new hardware finally (right after I installed it, so the discs aren't even marked yet):
New discs have an extra triangle-shaped vent hole the OEMs didn't have:
Close up of the mounting bobbins. There is a big flat washer between the disc and the wheel, the new supplied bobbin passes through the disc and has under its head a wavy spring washer, then a another flat washer against the disc. Reused the stock bolts with new loctite. When I removed the old bolts I cleaned them with a brass wire brush to get all the loctite off, and I ran an M8 tap into the each mounting hole on the wheel to clean out the old loctite. Before I put everything back together I checked to make sure the old bolts threaded in cleanly and smoothly by hand.
I will say there was some confusions that made this job take longer than it should have. Namely, Galfer included ten small flat washers and ten wavy spring washers with each disc. The best instructions I could find for mounting were only for the wave rotors on a BMW, not the regular round ones like these, and those instructions very clearly said to only use five small flat washers and wavy spring washers on each disc, just on the outside, under the bobbin, like in the photo. Not entirely trusting that, I played with measurements and my calipers for about an hour deciding if a matching pair of washers should be on the other side of the disc too. Atfter determining that there was essentially not room for this to be possible, I installed per the directions for the wave rotors, and now have leftover washers and wavy washers should I need to do the install again.
Not even scuffed in this photo, but I've since put >100 miles on them. Still bedding in -- gonna take a long ride today and see if the slight vibration band between 25-15 gets any better as everything mates together.
