I can't answer for Shelbs, but I had my brake replaced at Pep-Boys in Phoenix AZ, the OEM rotors were put back on as far as I know, not lowered, not sure what the addeco swaybar is, factory wheels. They did the brakes there, I know I paid a good bit for some "Super Ceramic Brake Pads? (guaranteed to not make noise and last longer then regular ones)" Not sure but they said they were some new top of the line something or other. Tie-Rod ends and ball joints seem good. Not really sure, everyone thinks I'm crazy, but I definitely hear it.. I'm guessing because I'm the one who spends most of the time in the car so it's easier for me to notice it?
