The disc and hat assemblies mount on the retained factory hubs; supplied register rings and shims establish the required rotor and radial-caliper alignment. Bill Wood established Wilwood Engineering in 1977. From 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\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003ch3\u003eKit contents and separate parts\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-18256-DR\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: included; DOT-compliant hoses\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eThis front conversion is the 12.88-inch Superlite configuration for the 1999–2002 Nissan Skyline R34. The original hubs remain in place beneath the aluminum hats; inspect their registers and wheel studs before fitting the adapters. Use the supplied stainless braided hoses, checking both full steering lock and suspension movement after connection. The guide describes the necessary dust-shield modification and radial bracket alignment. A wheel that meets the nominal diameter requirement still needs to match this kit's spoke and barrel clearance diagram. 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\u003eRotors and mounting dimensions\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRotors: 12.88 in; 327.15 mm diameter x 1.25 in; 31.75 mm thick; vented Spec-37 Iron\u003c\/li\u003e\n\u003cli\u003eFriction faces: SRP Drilled \u0026amp; 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; 0.595-inch hat offset\u003c\/li\u003e\n\u003cli\u003eRotor\/hat wheel-stud clearance patterns: 4 x 4.5 in; 4 x 114.3 mm; 5 x 4.5 in; 5 x 114.3 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCalipers and pads\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCalipers: FNSL6R; 6 pistons\u003c\/li\u003e\n\u003cli\u003eCaliper finish: Red 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: 1.75 \/ 1.25 \/ 1.25 in\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\/ds1690.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.
