Yep, that's what I was getting at.

To check more of the basics, is the slot in the rear caliper lined up with the post on the back of the inboard pad?

That's correct. I always double check that through the window in the caliper.

Although, come to think of it, I might have run a couple of track days with that caliper before I put ducts on the car.

The shaving thing is a non-issue, you can order pads in the correct thickness or rotate through pads once you've spent fifteen minutes orbital sanding your first set of full thickness pads

Agreed, I've even shaved pads on concrete by rubbing them in a figure 8 pattern before in a pinch. The Urge rotors are quite expensive though, and losing 4mm of pad material is a fair amount.

As for killing the calipers - overextension and heat seems to be what kills them, I seemed to make my rear calipers last longer when I stopped trying to get every last mm out of my pads.
