Built for oval, dirt and off-road use, and one of the compounds Wilwood specify as safe on titanium rotors. Strong friction with a flatter curve than BP-30.
Operating range88–649°C
Friction µ0.43–0.53
Pad lifeWear Rate: Medium-Low (published qualitative, fl227). 'Long wear rates with iron and steel rotors.' No quantified figure - NOT PUBLISHED.
These are the compounds we stock for the Wilwood Dynalite Single / Dynapro Single 6812 whose published friction and operating temperature come closest to Wilwood BP-40. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.

Very close
300–800°Cµ 0.42–0.55
Project Mu’s Club Racer. A strong trackday pad, but with a 300°C floor it is the range’s worst choice for a cold first lap.
