{"product_id":"wilwood-140-18366","title":"Black Wilwood FNSL6R GT Slotted Kit for Roadster Shop Mustang II Spindles — 12.88-inch Front Brakes","description":"\u003cp\u003eThe Roadster Shop Superlite front package combines black six-piston calipers with 12.88-inch GT rotors. The 1.10-inch-thick Spec-37 discs use flared aluminum hats and BP-10 pads, with radial brackets locating the calipers on the specified upright. Wilwood Engineering designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977; it is based in Camarillo, California, and serves motorsport, street-performance and specialized applications.\u003c\/p\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eThe Superlite front brackets are made for the Roadster Shop Mustang II spindle\/upright with the specified five-on-4.75-inch hub. Check that hardware first, then compare the 12.88-inch rotor and radial caliper envelope with the wheels. This application depends on the Roadster Shop components rather than an original Mustang model year. Follow the guide's steering-arm bracket orientation, rotor registration and shim procedure. Compatible hubs stay on the vehicle, and neither replacement hubs nor spindles are included. Hydraulic flexlines must be selected separately for the installed suspension. Nominal minimum wheel diameter: 17 in; 431.8 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003ch3\u003eCalipers and pads\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCalipers: FNSL6R; 6 pistons\u003c\/li\u003e\n\u003cli\u003eCaliper finish: Black Powder Coat\u003c\/li\u003e\n\u003cli\u003eBody construction: Forged aluminum\u003c\/li\u003e\n\u003cli\u003ePistons: stainless\u003c\/li\u003e\n\u003cli\u003eMounting: radial\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eIncluded pad compound: BP-10\u003c\/li\u003e\n\u003cli\u003eListed piston bore sizes: 1.62 \/ 1.12 \/ 1.12 in\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eRotors and mounting dimensions\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRotors: 12.88 in; 327.15 mm diameter x 1.10 in; 27.94 mm thick; vented Spec-37 Iron\u003c\/li\u003e\n\u003cli\u003eFriction faces: GT Slotted\u003c\/li\u003e\n\u003cli\u003eRotor coating\/finish: Black Electro Coat\u003c\/li\u003e\n\u003cli\u003eInternal vanes: 48 curved\u003c\/li\u003e\n\u003cli\u003eHats: Aluminum; Black E-Coat; 1.500-inch hat offset\u003c\/li\u003e\n\u003cli\u003eRotor\/hat wheel-stud clearance patterns: 5 X 4.5 in; 5 X 114.3 mm; 5 X 4.75 in; 5 X 120.65 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKit contents and separate parts\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-18366\u003c\/li\u003e\n\u003cli\u003eSupply: one brake kit; components for both sides of the axle\u003c\/li\u003e\n\u003cli\u003eMounting hardware: included\u003c\/li\u003e\n\u003cli\u003eHubs: not included\u003c\/li\u003e\n\u003cli\u003eSpindles, master cylinder and brake booster: not included\u003c\/li\u003e\n\u003cli\u003eBrake flexlines: not included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInstallation documents\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1701.pdf\"\u003eInstallation instructions\u003c\/a\u003e\u003c\/li\u003e\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.
