Our 2-piece, fully floating assemblies help shed unsprung weight and rotating mass from the front axle of the vehicle.\u003c\/p\u003e \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 D2-282) when they need to be replaced.\u003c\/p\u003e \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 \u003cp\u003eThe minimum thickness at which we recommend replacing these rings is 22mm. We also recommend replacing them if a crack leads to the edge of the ring.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSold and priced per pair.\u003c\/strong\u003e\u003c\/p\u003e                     \u003c!-- snippet location product_description --\u003e","brand":"Girodisc","offers":[{"title":"Default Title","offer_id":53286068060442,"sku":"A2-282","price":1350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/5105\/5642\/files\/Stock_photo_-_assemblies__05148.1705000471.jpg?v=1793637704","url":"https:\/\/race-centric.com\/products\/girodisc-bmw-g8x-m2-m3-m4-370mm-rear-rotors","provider":"Racecentric","version":"1.0","type":"link"}
