{"product_id":"wilwood-160-16923","title":"Wilwood GT 40-Vane Snap-Ring Rotor, 11.75 x 0.81 Inches","description":"\u003cp\u003eThe straight 40-vane core makes this GT rotor non-directional, while its eight internal drive lugs establish a specific mounting interface. At 11.75 x 0.81 inches, it is the thinner Spec-37 option for a compatible snap-ring retained assembly. Wilwood’s calipers, rotors, master cylinders, valves, fittings and lines support complete disc brake systems rather than an isolated component choice. Founded in 1977 by Bill Wood and based in Camarillo, California, the company designs and manufactures these systems for motorsport, street performance and specialized applications. Correct pairing of the rotor with its surrounding hardware is essential.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 160-16923\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e One rotor; not an axle pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside diameter:\u003c\/strong\u003e 11.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal thickness:\u003c\/strong\u003e 0.81 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor material:\u003c\/strong\u003e Spec-37 Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e 40 vanes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriction surface:\u003c\/strong\u003e GT Slotted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate weight:\u003c\/strong\u003e 9.80 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory burnished:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation orientation:\u003c\/strong\u003e Non-directional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor attachment pattern:\u003c\/strong\u003e 8 x 7.18 inches, lug\/snap-ring mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegistration \/ lug inside diameter:\u003c\/strong\u003e 6.53 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFar-side inside diameter:\u003c\/strong\u003e 8.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended use and restrictions:\u003c\/strong\u003e Suitable for high-temperature racing and street use.
