These are 390mm in diameter versus the 380mm rear rotors used in the standard brake package. They are a direct replacement for the factory carbon ceramic rotors. When used with our rear pads, the conversion does not require any modifications to the calipers or other components.\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 D2-206) 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\u003e\u003cstrong\u003eDiameter:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e390mm\u003cbr\u003e\u003cstrong\u003eThickness:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e34mm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eTBC lbs per rotor assembly\u003c\/p\u003e\n\u003cp\u003eThe minimum thickness at which we recommend replacing these rings is 32mm.
