Castrol SRF seems to have the highest boiling points, but it's very expensive.
Both Motul fluids and the both Ate Super 200 and Super Blue are the ones to go for.
"For race applications, vehicle owners will often alternate fluid flushes between Ate
Super Blue Racing Brake Fluid and Ate TYP 200 Amber Brake Fluid. The identical
specifications of the fluid and color difference make it easy to know when the old
fluid is completely flushed out of the system."
