Baer brakes on the awd shortened my stopping distance from 60-0 in 95ft. Original brake set-up from 60-0 took over 130ft. I find there is more of a fade difference in the pads and rotors than anything to do with the calipers. Stock pads have decent initial bite but poor fade, whereas the racing pads give up some initial bite for increased fade resistance. And then bigger rotors, of course, can dissipate more heat.
