The Wilwood BP-40 pad set, part 150-40-6812K, is four racing pads cut to the 6812 pad plate and built for Wilwood's Dynalite and Dynapro Single calipers. The manufacturer describes BP-40 as a high-friction compound with an aggressive initial bite, good low-temperature response, and high heat fade resistance. For sprint, dirt, and road-course teams that see repeated hard stops, that combination is the reason to pay more than a street pad costs. The manufacturer also notes low wear under sustained high heat and predictable, linear modulation, which helps a driver trail-brake consistently lap after lap. It is rated for steel, stainless, iron, super alloy, and titanium rotors, so one compound can cover several rotor choices.
Fitment is driven by the caliper, not the vehicle. The manufacturer's 6812 plate table lists Billet Dynalite Single, Dynalite Single 4, Dynalite Single Floater, Dynalite Single IIIA, Dynapro Single, Dynapro Single LW, Dynapro Single Polished, and Dynapro Single VW as compatible, so confirm your exact caliper model before ordering. Pad swaps are a straightforward bench-and-track job: pop the pad retainer clips, slide out the pins, insert the pads friction side toward the rotor, and check that pad height sits flush with the rotor's outer diameter. The manufacturer states these pads are racing only and not for street use, and its race bedding procedure is a must before hard service. Search terms for this part include BP-40 racing brake pads, 6812 pad plate, Dynalite single caliper pads, Dynapro single brake pads, and titanium rotor racing pads.
The manufacturer specifies that BP-40 is a racing-only compound and is not intended for street use. Use these pads only in competition or track applications.
The manufacturer's fitment table for the 6812 plate lists the Dynalite Single and Dynapro Single caliper variants, including Floater, IIIA, LW, Polished, and VW versions. Match your exact caliper model to that list before ordering.
Yes. The manufacturer's race bedding procedure calls for low-speed testing first, followed by a controlled heat cycle, because hard service from the start can cause pad fractures or accelerated deterioration. The manufacturer also offers a dyno-bedding service for pads and rotors.
The manufacturer's assembly sheets for its caliper kits say installation should be done by someone experienced with disc brake systems, and they recommend photographing the brake system before disassembly. Basic tools cover the pad retainer clips and pins, and the caliper bridge retainer where applicable. Keep brake fluid off the pad and rotor contact surfaces, use a catch bottle with a hose during bleeding, and fill the system with Hi-Temp 570 grade fluid or higher. The manufacturer does not recommend silicone DOT 5 fluid for racing or performance driving. After installation, the manufacturer advises bedding the pads on a race track or at a dyno service before hard use. Blocking brake cooling ducts can help the pads and rotors reach temperature faster during bedding.
