Ive never really given a big brake kit much thought. The factory brakes or any brakes can only stop you as fast as the tires have traction. Once that ABS lights up, thats it. The advantage of the bigger brakes is heat dissipation on long repeated stops with high speeds. Ive never felt any brake fade with the stockers. I have seen videos where the big brakes show a clear stopping advantage in Raptors, but they were running different wheels and tires with likely different coefficients of friction. A higher traction/heavier wheel tire combo (37s) likely would be able to take advantage of bigger better brakes, but from where Im sitting, not really with lighter weight methods and KO2s. YMMV
