I am running with AP racing brakes,the rear ones of 13 inch brake squeaking so hard. I have tried many stores and they all said it is because of the material of metal of the pads,it might be ok if I change to normal street pads.So I am looking for the normal pads which could be the same size as the current ones so that can be fit in the AP CALIPER. the pad part number is FRP219H.Dose anyone know?Thanks a lot
