{"product_id":"wilwood-140-12435-r","title":"Wilwood GT Slotted 12.88-Inch Rear Disc Kit, Red, Strange Floater 3.49-Inch Offset","description":"\u003cp\u003eThis red-caliper Wilwood rear kit is built around 12.88-inch GT slotted rotors and the Strange Engineering floater interface. Four-piston Superlite calipers provide the service-brake function; internal shoes supply the mechanical parking brake. A measured 3.49-inch flange offset is required, so wheel and axle geometry should be confirmed before selecting the assembly. 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: 140-12435-R\u003c\/li\u003e\n\u003cli\u003eType: Forged Narrow Superlite 4R Big Brake Rear Parking Brake Kit\u003c\/li\u003e\n\u003cli\u003eCalipers: Forged Narrow Superlite 4R; 4 pistons per caliper; Red Powder Coat.\u003c\/li\u003e\n\u003cli\u003eCaliper bore sizes: 1.25, 1.25 inches.

Verify that the existing floater hub supports the hat mounting, then compare the wheel's barrel and spokes with the complete caliper envelope. Arrange hydraulic lines and parking-cable hardware independently. Cable routing should avoid sharp turns, and the chosen master cylinder must suit the combined front and rear caliper volumes.\u003c\/p\u003e\u003cp\u003eWilwood installation documents: \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds894.pdf\"\u003eInstallation instructions\u003c\/a\u003e; \u003ca href=\"https:\/\/www.wilwood.com\/Images\/BrakeKits\/Axle-Offset-Worksheet-Wilwood.pdf\"\u003eTechnical bulletin\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003ePMB Performance has over 20 years of brake-system experience.
