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-28 brake pads in the 0.65-inch XRS4R/XRS6R configuration supply four replacement pads. Every component must suit the complete brake system in which it operates.
BP-28 changes its friction behavior with rotor material and temperature: Wilwood describes medium-high friction on hot titanium or stainless rotors and medium friction at lower-to-medium temperatures on steel or iron. Its competition uses include sprint/midget, dirt oval, lighter road-course cars, drag and off-road applications. Material choice also affects wear, particularly with titanium.
