I think the idea is to swap everything out for 100 series components. The rotors are roughly 1/2" larger in diameter, the rotors are 2-4 mm thicker. The pads have more surface area. The 80 pistons are 45mm and the 100 uses 2 45mm and 2 51mm pistons. you get more clamping pressure, more surface...
My brakes don't warp or overheat so my problem was getting enough line pressure from the vacuum assist. Swapped over to Hydro Boost and the thing stops on a dime. I'm running 37's without any issues and I live in the rockies.
