I've just replaced my stock front brakes with the ebc hh, Are you supposed to use the factory shims or the shims/heat dissapator thingys that come with the ebc h's or both? I only used the ones that came with the new pads . Beginning to wonder if I screwed up???Because the new brakes are loud as heck, but I'm hoping that will stop once they have seated to the rotors??? HELP!!! thanks!! Yes they do stop better already..
