Its 72-vane, 1.25-inch-thick discs mount to the original hubs through aluminum hats, and braided flexlines are included. 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: 140-18253\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\u003eThe 14-inch FNSL6R package retains the front hubs of the specified 1995–1998 Skyline R33. Verify the hub register, stud clearance and wheel envelope before installing the two-piece rotor assemblies. The guide calls for dust-shield trimming and careful alignment of the radial caliper brackets. Included braided hoses connect the calipers to the vehicle; support them so they cannot rub the tires or become tight at full travel. This R33 configuration uses the piston sizes and mounting hardware listed above, so selection should follow the exact kit guide rather than rotor diameter alone. Nominal minimum wheel diameter: 18 in; 457.2 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: 14.00 in; 355.6 mm diameter x 1.25 in; 31.75 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: 72 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: 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-20\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\/ds1688.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.
