{"product_id":"wilwood-140-12877-dr","title":"Wilwood Rear Red Four-Piston Caliper\/Rotor Conversion, Subaru Impreza WRX (2008–2014), 12.88-Inch Drilled Friction Rings","description":"\u003cp\u003eRed Superlite 4R calipers distinguish this drilled\/slotted rear package for the supported Subaru Impreza WRX configurations. The 12.88-inch rings mount on separate hats designed to work with the original parking brake. This conversion supplies the hydraulic braking components and rear lines; it does not replace the need for serviceable original parking shoes, cables and hub hardware. Wilwood Engineering was founded by Bill Wood in 1977 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.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-12877-DR\u003c\/li\u003e\n\u003cli\u003eType: Forged Narrow Superlite 4R Big Brake Rear Brake Kit For OE Parking Brake.\u003c\/li\u003e\n\u003cli\u003eCalipers: Forged Narrow Superlite 4R; 4-piston; Red Powder Coat.\u003c\/li\u003e\n\u003cli\u003ePiston bore dimensions: 1.12, 1.12 inches; stainless pistons.
