OEM shims are probably physically compatible if the pad shape is the same but I presume they're made of steel. Titanium on the other hand is a poor heat conductor and will help prevent hot pads from transferring heat into the pistons.

Mine are showing up today, hope I can find some time to install them and do an oil change this weekend.

I’ve got access to bucket loads ti40, 70, 6al4v etc in various gauges. Are the shims flat or with simple forming, or is a form tool required?

No forming, they're dead flat. Do you need dimensions or are you just going to trace a pad onto the flat stock?

the ACRE are 0.75mm thick, about .031"

Your numbers are a little off there. 3/4 of a millimeter is not .031", it's only 0.0295. One or the other might be correct, but not both.

That's a difference of 0.0015"
That's literally 1.5 thousandths of an inch, well within the tolerance of a set of plain digital calipers. I switched modes and took another measurement, so it may have been a hair off zero.

I've ordered the Endless Super Street M-Sports Plus from Black HawkJapan a week ago and received an email today that states that they are order-made, and that it will take 1.5 months to manufacture them.

Did anyone else received something similar from Black Hawk Japan?

I got a similar message, and they shipped in about two weeks. They may actually be backed up that far, its always a possibility, but hopefully yours will ship sooner.

For those with the endless ss m-plus, did the front pads all look the same?

The stock inner pads have like wings at the bottom.

They fit without a problem, just checking.

Those chamfers are to help reduce squealing by preventing brake dust buildup on the leading edge. Different manufacturers have different methods (angles, placement, etc) as you can see, but its all for the same purpose. They don't affect the braking performance at all.

edit- or if you're talking about the notch on the backing plate, I don't think it affects anything, maybe just a manufacturing step to attach a wear indicator. I'm pretty sure that area of the backing plate doesn't even interact with anything, it just hangs there.
