Improve heat tolerance
New brake fluid will increase the boiling temp by 100C compared with old fliud, racers change theirs every race.
Use high temp brake pads, normal ones will melt and disappear.
Improve heat removal
Higher temps will lose heat at a higher rate, so the above improvements will also benefit removal.
Use a thick new brake cover plate like the mgb ones, it acts as a heat sink to the caliper , ensure good thermal coupling, M7 bolts.
Cut a section from the disk cover and convert to an air scoop, perhaps add a mesh to stop stones entering. Consider ducts from the valence.
Use metal braided brake line
Use a looping brake circuit to allow fluid circulation via the bleed valve. Pumps and heat sinks maybe available.
Use drille dimpled disk.
Make sure rears are taking their share of the load.
Use alloy wheels with good thermal coupling between the hub and wheel, copper grease may help
Brake hard to encourage higher temps and longer cooling periods, the higher temps will be lost faster considering you have the same energy to dissipate.
Thermal cameras for your phone will be mainstream this year, buy one
