scottj ... several schools of thought on that . I worked with Roush Racing in Mooresville on my pad selection and their brake guy said I had to remove all the old pad material that was deposited by cleaning with Dawn detergent and scuffing the rotor with 100 grit paper , cleaning again and then bed the new pads in . These are strictly race only pads and can never be used on the street . Howevere , I will say that the car stops like it hit a brick wall ...... time and time again with zero fade . The hotter they get , the better they stop and yet cold stops are pretty great too .
Others just change pads and go ... both seem to work ok .
