Weighing in at 12.4 lbs per rotor, these fully floating assemblies help shed unsprung weight and rotating mass from the rear axle of the vehicle.\u003c\/p\u003e\n\u003cp\u003eThe rotor rings are machined from a proprietary casting made of high-carbon iron formulated to GiroDisc’s specifications. This superior metallurgy results in a rotor that holds up better, and the 48 curved vanes act as a centrifugal pump pulling air in through the hub to effectively cool the rotors under hard use. The 2-piece design means a reusable hat which can be attached to new rings (part number D2-324) when they need to be replaced.\u003c\/p\u003e\n\u003cp\u003eAll major components including the hats, rotor rings, and drive pins are manufactured in-house at our facility in Bellingham, WA from domestically sourced materials. The hat is made from 6061-T6 aluminum and coated in a black anodize finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and Belleville washers for race-ready float while also being street-friendly with no noise from loose hardware.\u003c\/p\u003e\n\u003cp\u003eDiameter: 330mm\u003cbr\u003eThickness: 26mm\u003cbr\u003eWeight: 12.4 lbs per rotor assembly\u003c\/p\u003e\n\u003cp\u003eThe minimum thickness at which we recommend replacing these rings is 24mm. We also recommend replacing them if a crack leads to the edge of the ring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment Note:\u003c\/strong\u003e\u003cspan\u003e These C6 Z51 rotors can be used on C5 and C6 base cars with the Z51 rear caliper bracket (GM part # 88964167) or equivalent. The bracket works with the existing calipers and these rotors to complete the conversion to the Z51 brake package.\u003c\/span\u003e\u003c\/p\u003e","brand":"GiroDisc","offers":[{"title":"Default Title","offer_id":51080860565824,"sku":"GIRA2-324","price":995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0704\/7587\/4624\/files\/408mm72v__60624_4f75e064-c49f-4334-9be1-6d389f61e76f.jpg?v=1758652794","url":"https:\/\/www.forzamotorworks.com\/products\/girodisc-2-piece-rear-rotors-c6-corvette-z51-2005-2013","provider":"Forza Motor Works","version":"1.0","type":"link"}
