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.

Fitment & Compatibility

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.
