{"product_id":"wilwood-160-9239ls","title":"Wilwood Front GM Metric Modified Hub Rotor, 10.50 x 1 Inch, Long Studs","description":"\u003cp\u003eLong 3.14-inch wheel studs distinguish this LS hub rotor for GM Metric Modified racing installations. The 10.50 x 1.00-inch iron rotor includes installed bearing races and a five-on-five-inch stud pattern, while bearing and spindle hardware are selected separately. 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 160-9239LS\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 10.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal thickness:\u003c\/strong\u003e 1.00 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 Plain Face\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 14.90 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 Non-directional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFar-side inside diameter:\u003c\/strong\u003e 8.87 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub wheel bolt pattern:\u003c\/strong\u003e 5 x 5.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstalled wheel studs:\u003c\/strong\u003e 5\/8-11 coarse thread, 3.14-inch length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstalled races:\u003c\/strong\u003e Included; bearing cones and installation kit sold separately\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended use and restrictions:\u003c\/strong\u003e GM Metric Modified rotor for dirt and asphalt racing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eOne hub and rotor with installed bearing races and long wheel studs.
