{"product_id":"wilwood-120-9703","title":"Wilwood Black DynaPro Caliper for 0.81-Inch rotor width, Four 1.38-Inch Pistons","description":"\u003cp\u003eFour 1.38-inch stainless pistons give this black DynaPro its 3.00-square-inch published piston area. The forged body is the nominal 0.81-inch rotor-width version with 5.25-inch lug centers. It is intended as a matched component in a brake package whose hydraulic and mounting dimensions are already established. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-9703\u003c\/li\u003e\n\u003cli\u003eCaliper type: Dynapro Lug Mount\u003c\/li\u003e\n\u003cli\u003eConstruction: Forged Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Black Powder Coat\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.38 \/ 1.38 inches\u003c\/li\u003e\n\u003cli\u003ePiston type: Stainless\u003c\/li\u003e\n\u003cli\u003ePiston count: 4\u003c\/li\u003e\n\u003cli\u003ePublished piston area: 3.00 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.81 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 0.75–0.83 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter limits: 10.00–13.06 inches\u003c\/li\u003e\n\u003cli\u003eMounting style: Lug\u003c\/li\u003e\n\u003cli\u003eHandedness: Not restricted to one side; correct mounting and bleed orientation required\u003c\/li\u003e\n\u003cli\u003eMounting centers: 5.25 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole size: 0.39 inch\u003c\/li\u003e\n\u003cli\u003eMount height: 2.10 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRequired pad shape: 7812\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 6.36 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 2.1 cubic inches\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed component weight: 3.8 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eConfirm the rotor’s measured width and the bracket’s stand-off, then check the pad track against a suitable rotor diameter.
