{"product_id":"wilwood-150-13335k","title":"Wilwood GP320 Purple Brake Pads for Aluminum-Rotor Racing Systems","description":"\u003cp\u003eThe Purple friction material in this GP320 set is intended for sprint-car brake systems, including aluminum rotor applications. Its 0.44-inch pad profile is larger than the GP200 form, making exact caliper identification essential despite the shared compound color. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form Wilwood Engineering’s disc brake range. Bill Wood founded the Camarillo, California company in 1977; it designs and manufactures systems for motorsport, street-performance and specialized applications. Matching the component to the rest of the brake package is fundamental to selection.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 150-13335K\u003c\/li\u003e\n\u003cli\u003eFriction compound: Purple\u003c\/li\u003e\n\u003cli\u003ePackage quantity: 4 pads\u003c\/li\u003e\n\u003cli\u003ePad thickness: .44 inch\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 3.65 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 1.03 cubic inches\u003c\/li\u003e\n\u003cli\u003eRotor compatibility: Aluminum, Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003eBedding status: not pre-bedded; follow Wilwood bedding procedure\u003c\/li\u003e\n\u003cli\u003ePad profile: 6211\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003ePurple is a composite metallic racing compound developed for high-temperature durability on aluminum and other low-conductivity alloy rotors.

Verify the required new-pad thickness alongside the plate’s contact and mounting surfaces. Rotor material and operating temperature must also match the friction compound; a shape match alone is insufficient.\u003c\/p\u003e\u003cp\u003eReference: \u003ca href=\"https:\/\/www.wilwood.com\/BrakePads\/BrakePadsProd?itemno=150-13335K\"\u003eWilwood product specifications and compound guidance\u003c\/a\u003e. \u003ca href=\"https:\/\/www.wilwood.com\/Images\/BrakePads\/PadPlateDrawings-Large\/6211.jpg\"\u003eManufacturer profile illustration\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eNeed to resolve a pad-shape or compound question?
