Product details
The manufacturer, Wilwood Engineering, began under Bill Wood in 1977 and operates from Camarillo, California. It designs and manufactures disc brake systems and components: calipers, brake rotors, master cylinders, valves, fittings and lines for motorsport, street and specialized vehicles. BP-40 brake pads in the .49-inch Low-Profile Dynapro/DPC56 configuration supply four replacement pads. Individual parts must match the complete brake system and its operating requirements.
BP-40 provides an aggressive initial response and good low-temperature friction, followed by stable modulation under sustained racing heat. Wilwood lists steel, stainless steel, iron, Super Alloy and titanium rotor materials. This is a racing-only selection, not a street pad; temperature needs and system balance remain part of compound selection.
