I think maybe what I'll try is just getting rear shoes with some extra high coefficient of friction. Since my front pads are carbon with a somewhat low coefficient, maybe it will balance out.

I bet the shoes are about due for replacement now. And of course, I still haven't gotten around to flushing out the old fluid and replacing it with 500 degree stuff. Still not sure if it's better to bleed and bleed, hoping the old stuff all gets washed out, or go to the trouble of taking each wheel off and holding the cylinder upside down to drain. Maybe I should bleed and bleed, then drive a bunch to thoroughly mix any remaining old fluid with the new (including some ABS stops), then bleed and bleed again.
