BP-35 is a high-friction racing formulation with smooth, linear response and controlled release. Friction develops with heat, while Wilwood characterizes pad wear as low to medium. Use the compound with iron or steel rotors. Its road-course, oval and off-road racing roles do not establish suitability for street service.

Fitment & Compatibility

Use the 0.67-inch pad only in the listed AERO4, AERO6 and W-series configurations. The thicker 0.80-inch AERO option is a separate selection, even where the pad face appears similar.
