thanks for the info, but i'm not after squeal prevention, i'm after control over
heat transfer from the pads to the calipers. my wife checked with a co-worker
of hers, and he says that 1018 (conventional mild steel, probably your shims
are 1018 or 1020, more-or-less the same thing) has a thermal conductivity
of 47W/mK. 304 stainless has a thermal conductivity of 16W/mK (1/3 that of
mild steel.) 

i probably wouldn't work that hard to duplicate the shape of the top, i'd
just coat the pad backs with antisqueal goo and stick the stainless bit
on the back. at $6 for an 8" x 24" sheet, stainless shim costs are down
in the noise, i can afford to throw the shims away when i change pads if
i can't separate them. but thanks for the thickness, now i know i can
double the depth of the shim, which will cut heat transfer even more.

if there were a good way to get ceramics to work, my wife's co-worker
says that zirconium oxide (ZrO2) has a conductivity of 3W/mK.
