The biggest thing is getting cooling. Your stock brakes would work with the right pads as long as you have proper cooling( I.E big ducts routed directly to the rotors). Mustangs, Evo's, Sti's are a few that need LOTS of coolings and suffer big time without it. The problem is getting ducts to your brakes are hard which is why most people buy a BBK, but then you have $$ to spend on pads.Originally Posted by DieselNuts
