From Camarillo, California, the company designs and manufactures disc brake systems covering motorsport, street performance and specialized applications, with calipers, rotors, master cylinders, valves, fittings and lines in its product range. This rotor should be selected with the mounting arrangement, friction compound and hydraulic system in mind.
