{"product_id":"wilwood-160-9812-bk","title":"Wilwood Rear Right-Hand SRP Parking-Drum Rotor, 12.19-Inch Ring with 1.910-Inch Offset","description":"\u003cp\u003eThis right-hand SRP rear rotor includes a hat drilled for three wheel-stud clearance circles. Its 12.19-inch friction ring is cast with a 1.910-inch-offset center and 7.24-inch parking drum, defining the complete geometry of the replacement. Disc brake systems have been Wilwood’s focus since Bill Wood founded the company in 1977. Based in Camarillo, California, Wilwood designs and manufactures calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. The rotor is one part of that system and needs compatible pads, calipers and mounting components.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 160-9812-BK\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 12.19 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 Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e 32 vanes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriction surface:\u003c\/strong\u003e SRP Drilled \u0026amp; Slotted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Electro Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate weight:\u003c\/strong\u003e 14.40 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory burnished:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDynamically balanced:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation orientation:\u003c\/strong\u003e Right-hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegistration \/ lug inside diameter:\u003c\/strong\u003e 3.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFar-side inside diameter:\u003c\/strong\u003e 8.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor offset:\u003c\/strong\u003e 1.910 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal parking-brake drum diameter:\u003c\/strong\u003e 7.24 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal clearance diameter:\u003c\/strong\u003e 7.16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting-face thickness:\u003c\/strong\u003e 0.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHat wheel-stud clearance pattern:\u003c\/strong\u003e 5 x 4.50\/4.75\/5.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel-stud clearance hole diameter:\u003c\/strong\u003e 0.52 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpposite-hand companion rotor:\u003c\/strong\u003e 160-9813-BK (sold separately)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended use and restrictions:\u003c\/strong\u003e Register adapters from 2.00 to 2.86 inches are available separately.
