{"product_id":"wilwood-171-7671","title":"Wilwood Undrilled Short-Offset Hat with 2.40-Inch Register","description":"\u003cp\u003eA 0.725-inch offset and 2.40-inch register define this Wilwood hat. Its undrilled flange requires machining for the intended brake assembly. Wilwood Engineering’s work covers the design and manufacture of disc brake systems for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977 in a business now based in Camarillo, California. Its calipers, master cylinders, brake rotors, brake lines, valves and fittings must be selected around the complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 171-7671\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter register diameter:\u003c\/strong\u003e 2.40 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor mounting hole\/thread designation:\u003c\/strong\u003e 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal clearance diameter:\u003c\/strong\u003e 5.90 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting-face thickness:\u003c\/strong\u003e 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer-listed attachment hardware reference:\u003c\/strong\u003e 230-8390; verify the specific rotor and attachment arrangement before ordering hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent:\u003c\/strong\u003e Short-Offset Brake Rotor Hat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface finish:\u003c\/strong\u003e Black E-Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor mounting method:\u003c\/strong\u003e Fixed Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHat offset:\u003c\/strong\u003e 0.725 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor attachment interface:\u003c\/strong\u003e 8 x 7.00 inches; rotor attachment, separate from the hub flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub-flange mounting\/clearance pattern(s):\u003c\/strong\u003e Blank — flange requires machining\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eFor Custom big-brake systems, compare the replacement with the actual hat and complete brake-kit instructions. A matching flange pattern alone does not establish rotor alignment or caliper clearance. The blank hub flange is not ready to bolt on.
