{"product_id":"wilwood-150-9841k","title":"Wilwood Composite Metallic Racing Brake Pads for GNX4\/GNX5 Calipers — 0.57-Inch Set","description":"\u003cp\u003eThis GNX-profile set uses Wilwood's CM composite-metallic friction for racing service. The compound is specifically associated with sustained high heat and stainless-steel rotor applications, while the 0.57-inch plate must match the fitted GNX4 or GNX5 caliper. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications. Each part is selected to match the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 150-9841K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad type:\u003c\/strong\u003e CM replacement brake pad set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad profile:\u003c\/strong\u003e 9115\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 4 pads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Installation-dependent; confirm the actual caliper application\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal thickness (Wilwood specification):\u003c\/strong\u003e .57 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible rotor material:\u003c\/strong\u003e Steel, Stainless Steel, Iron, Super Alloy, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompound application:\u003c\/strong\u003e Racing only — not for street use\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriction characteristics:\u003c\/strong\u003e Composite metallic high-friction formulation for stainless steel rotors, with a smooth initial response and low wear during sustained high-heat braking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper selection:\u003c\/strong\u003e GNX4 and GNX5 calipers using the 9115 plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad area:\u003c\/strong\u003e 11.15 sq in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad volume:\u003c\/strong\u003e 4.07 cu in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory bedded:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublished weight:\u003c\/strong\u003e 6.800 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWARNING: This product can expose you to chemicals including Arsenic, Cadmium, Chromium (Hexavalent compounds), Lead, Nickel, Cobalt and Antimony Trioxide which are known to the State of California to cause cancer or other reproductive harm.
