These fully-floating assemblies help shed unsprung weight and rotating mass from the rear 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 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 \t\u003cstrong\u003eOuter diameter:\u003c\/strong\u003e 352mm\u003cbr\u003e \t\u003cstrong\u003eThickness:\u003c\/strong\u003e 22mm\u003cbr\u003e \t\u003cstrong\u003eMinimum thickness:\u003c\/strong\u003e 20mm\u003cbr\u003e \t\u003cstrong\u003eWeight:\u003c\/strong\u003e 14.3 lbs per rotor assembly\u003cbr\u003e \t\u003cstrong\u003eVane count:\u003c\/strong\u003e 48 curved vanes\u003cbr\u003e \t\u003cstrong\u003eReplacement rings:\u003c\/strong\u003e \u003ca href=\"https:\/\/girodisc.com\/audi-352mm-rear-replacement-rings\/\"\u003e\u003cu\u003eD2-187\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 \u003cp\u003e\u003cb\u003eWhy 352mm and not 356mm?\u003c\/b\u003e The factory rotors are advertised as having a diameter of 356mm.
