Product details
Wilwood Engineering of Camarillo, California dates to Bill Wood’s founding of the company in 1977. It designs and builds disc brake systems and the calipers, rotors, master cylinders, valves, fittings and lines used in motorsport, street and specialized brake installations. BP-40 brake pads in the .80-inch AERO4/AERO6 configuration supply four replacement pads. The complete braking arrangement determines which individual components are appropriate.

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.

The current compatibility list identifies AERO4 and AERO6 calipers for this 0.80-inch version. Check rotor width and caliper pad capacity before replacing a thinner AERO pad.
