I added nord-lock washers to the turbo flange nuts and wastegate mounting hardware on my rally car years ago- I spent a long time fighting with the hardware loosening with time and a bunch of heat cycles- might be something to consider while the motor is out and on a stand.  It's hard to tell how difficult that hardware is to access once it's in the car.   Beautiful motor, that's going to be sick!

From the bottom of the pad to the shoulder

Overall thickness of the pad. 
 

Took me longer than I'd anticipated to get out to the garage. Sorry about that!

The stock brakes found on the 1991 Audi 200 20v are referred to as the UFO brake system. It was a unique rotor and caliper solution.

 

Just a quick note to let you know that it wasn't a unique braking solution. It had been tried in the '50s and was abandoned in the '60s.

I was really surprised to see this in your post, as I had no idea it was ever revived.
