This superior metallurgy results in a rotor that better withstands hard use, and the curved vanes act as a centrifugal pump pulling air in through the hub to cool the discs. The 2-piece design has a reusable hat which can be installed onto new rings 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 spring washers for race-ready float while also being street-friendly with no noise from loose hardware.\u003c\/p\u003e \u003cp\u003e \u003cstrong\u003eOuter diameter:\u003c\/strong\u003e 380mm\u003cbr\u003e \u003cstrong\u003eThickness:\u003c\/strong\u003e 32mm\u003cbr\u003e \u003cstrong\u003eMinimum thickness:\u003c\/strong\u003e 30mm\u003cbr\u003e \u003cstrong\u003eWeight:\u003c\/strong\u003e 23.1 lbs per rotor assembly\u003cbr\u003e \u003cstrong\u003eVane count:\u003c\/strong\u003e 72 curved vanes\u003cbr\u003e \u003cstrong\u003eReplacement rings:\u003c\/strong\u003e \u003ca href=\"https:\/\/girodisc.com\/porsche-380mm-rear-replacement-rings\/\"\u003e\u003cu\u003eD2-146\u003c\/u\u003e\u003c\/a\u003e \u003c\/p\u003e \u003cp\u003eWe recommend replacing the rings when they reach minimum thickness or if a crack forms leading to the edge of the ring.\u003c\/p\u003e \u003c\/div\u003e","brand":"GiroDisc","offers":[{"title":"Default Title","offer_id":67897390170357,"sku":"A2-146","price":1750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/6757\/6821\/files\/408mm72v__00161.1677861671.webp?v=1793383718","url":"https:\/\/millaracing.com\/products\/girodisc-porsche-991-gt3-rear-rotors","provider":"Millaracing","version":"1.0","type":"link"}
