Given what Porterfield charges, I'd say that is an understatement.

Well, if you try to fit a pad that is overall too thick, on a UFO
brake setup the pad will collide with the inside edge of the rotor at
the corners as you try to reinstall the rotor over the "outboard" pad.

They weren't bevelled at all- the surface was flat. I had to bevel
them to make them fit, by perhaps 2-3MM. That is a substantial error
on a pad that has what...10-12MM of material on it?

Well, in my case- there wasn't any way for them to make right, as I
discovered the problem about 30 minutes before my first rungroup.
Missed at least a half hour of track time at the ONE event I
attended last year...
