Wilwood BP10 Round Brake Pads for Billet Spot Calipers

This BP10 set uses the round, two-hole pad form required by the Billet Spot caliper. Four 0.35-inch pads are supplied, so verify the caliper's round pocket and retention arrangement rather than selecting a rectangular Wilwood pad by thickness alone. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and related components. Bill Wood founded the company in 1977. The range spans motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines that must be chosen to suit the complete system.

Fitment & Compatibility

Wilwood’s compatible-caliper list names Billet Spot. Pad retention, backing-plate dimensions and the available thickness clearance are the critical mechanical checks. Identify the caliper actually fitted to the vehicle, especially where a previous brake conversion has changed the original equipment.

A modest heat requirement is central to choosing BP10: the compound is suitable for street use, drag racing and light-to-medium braking on dirt. It works with steel and iron rotors and offers gradual response with low dust and noise ratings, rather than the aggressive behavior of a dedicated high-temperature race pad.
