I have found that running with a .035 in. stainless shim behind the pad,
helps to shield the heat from getting into the caliper. You may have to
wear the pads in a bit before it will go in, but it worked well for me.
I just cut it out with a dremel tool to the same outline as the backing
plate. Some of my friends have had them made out of .035 titanium.
