{"product_id":"wilwood-120-16683-rd","title":"Wilwood FNSL4R Brake Caliper, Red, 0.95-Inch Rotor Width","description":"\u003cp\u003eThe rotor and bracket determine whether this red Wilwood FNSL4R brake caliper is the correct choice. Its 0.95-inch rotor-width configuration works with the radial mount and 4-piston layout detailed below. The Wilwood disc brake range is designed and manufactured for motorsport, street-performance and specialized applications. It includes brake lines, fittings, valves and master cylinders together with calipers and brake rotors. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California; its components must be matched to the complete braking system. The Forged Narrow Superlite 4R is a four-piston radial caliper using the 7416 pad outline. Its nominal 0.95-inch-wide rotor configuration must be matched to the mounting height and hydraulic balance of the installation. Wheel clearance is determined by the entire caliper-and-bracket envelope.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-16683-RD\u003c\/li\u003e\n\u003cli\u003eComponent: Forged Narrow Superlite 4 Radial Mount; one individual caliper\u003c\/li\u003e\n\u003cli\u003ePlacement: Universal mounting orientation; verify axle position\u003c\/li\u003e\n\u003cli\u003eConstruction and finish: Forged aluminum; Red Powder Coat\u003c\/li\u003e\n\u003cli\u003eMounting interface: Radial; mounting centers 5.98 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.39 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 1.45 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003ePistons: 4; stainless steel; bore dimensions 1.38\/1.38 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 3.00 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 7416; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.95 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 0.89–0.99 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 11.42–14.00 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 5.0 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCheck bracket location and rotor sweep using the installation drawing; 5.98-inch radial mounting alone does not establish a vehicle fit.
