Interesting- that's 180° outta phase with my own experience with the Porterfields; had a local shop take a light cut off the front rotors just to clean them, and the bite has been outstanding- hot or cold- since Day One.stevedelegard said:This is my experience with Porterfield pads - tried them out becuse others were raving about the performance. At 200 bucks for all 4 wheels they have to be fantastic super pads. Not! These things are for racing - probably takes high heat really well. For street driving they are a joke- twice the pedal pressure for a quick stop.
