The Wilwood BP-40 6211 pad set (part 150-40-6211K) is a race-only friction pad built for Wilwood's GP320 billet four-piston caliper, which runs the 6211 pad plate. The BP-40 compound is designed for a strong initial bite, good cold-weather response, low wear during sustained heavy braking, and high heat fade resistance. It suits sprint car, midget, mini-sprint, and formula sports racing, along with road course, pavement oval, dirt, and off-road use. A stock street pad will not match the GP320 plate or hold up to repeated high-temperature stops, so this set is the right choice for a competition caliper, not a street upgrade. The 0.44-inch thick pad offers about 3.65 square inches of friction area, which Wilwood says is nearly 50% more than some popular two-piston calipers.
Shoppers searching for GP320 6211 brake pads, BP-40 racing brake pads, Wilwood sprint car brake pads, or midget brake pad replacement will find this set matches those applications. Before you order, confirm your caliper is a GP320 with the 6211 plate, since the manufacturer's documentation lists more than one GP320 version and rotor clearance varies by version. These pads ship unbedded, so follow Wilwood's bedding procedure before running them hard on track. Plan for a full pad change and rotor check when you install them, and inspect the caliper pad retainers and bleed screws during service.
The manufacturer lists this BP-40 6211 pad as racing only and not for street use, so it is intended for competition applications.
