Have you considered making backing plates out of stainless, and then having a
brake company attach friction compound to them? I just had a set of brake
pads made for my track-day car (Alfasud Sprint w outboard front brakes) for
the same price as off the shelf race pads, were off the shelf pads available.
The brake shop burnt the old material off an old set of pads, then attached
the new race quality friction compound to those backing plates. I wonder if
it's worth making stainless backing plates when I have a second set made up.
