The rotor rings are machined from a proprietary casting made of high-carbon steel 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 D1-307) 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 34mm. 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","brand":"Girodisc Racing Brakes","offers":[{"title":"Default Title","offer_id":50468354031933,"sku":"A1-307","price":2576.42,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/7548\/3197\/files\/GIR-0018690.png?v=1751786208","url":"https:\/\/www.modsdirect.com.au\/products\/a1-307","provider":"ModsDirect","version":"1.0","type":"link"}
