There still is a question of what the overall mean temp is of the caliper and rotor is, however, there is no question the rears run hotter than the fronts, even with the electronic nannies off.
If you have the front pfc bbk and stock rear rotor then for sure your rear runs hotter than your front

On my e90 with the full bbk the rear is cooler. It is less efficient and singing the hair straight off my legs
