Our 2-piece, fully floating assemblies utilize the factory calipers and require no modifications other than switching the rotors and pads. These rotors use the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003efactory iron pad shape with the carbon ceramic calipers\u003c\/strong\u003e. Please contact us if you need help finding pads.\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 72 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 D1-220) 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\u003eThe minimum thickness at which we recommend replacing these rings is 34mm. We also recommend replacing them if a crack leads to the edge of the ring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSold and priced per pair.\u003c\/strong\u003e\u003c\/p\u003e","brand":"GiroDisc","offers":[{"title":"Default Title","offer_id":48491593826549,"sku":"A1-322","price":1450.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/9522\/9173\/files\/408mm72v_0020__15606.jpg?v=1785415824","url":"https:\/\/cicioperformance.com\/products\/bmw-g8x-m3-m4-front-iron-rotor-conversion","provider":"Cicio Performance","version":"1.0","type":"link"}
