Each rotor pairs GiroDisc's proprietary cast iron disc, poured and machined entirely in the USA, with a 6061-T6 aircraft-specification aluminum hat section for significant unsprung weight reduction over the OEM cast iron unit. The floating mount system using 10 high-strength cadmium-plated alloy steel drive pins allows thermal expansion without warping, eliminating the heat-induced brake pedal pulsation common with conventional one-piece rotors during hard track use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e2-piece fully floating rear brake rotor design for the Ford Focus RS Mk3\u003c\/li\u003e\n\u003cli\u003eProprietary cast iron disc poured and machined in-house at GiroDisc in the USA\u003c\/li\u003e\n\u003cli\u003e6061-T6 aircraft specification aluminum hat for reduced unsprung and rotating mass\u003c\/li\u003e\n\u003cli\u003e10 high-strength alloy steel cadmium-plated drive pins for thermal float\u003c\/li\u003e\n\u003cli\u003eSlotted disc design improves bite, outgassing, and pad face cleaning under heavy braking\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on replacement for OEM Focus RS rear rotors, no modifications required\u003c\/li\u003e\n\u003cli\u003eCompatible with OEM and aftermarket Focus RS rear calipers\u003c\/li\u003e\n\u003cli\u003eSignificantly reduced warping and pedal pulsation compared to one-piece rotors\u003c\/li\u003e\n\u003cli\u003eSold as a pair (both rear rotors included)\u003c\/li\u003e\n\u003cli\u003eDesigned, manufactured, and assembled in the USA by GiroDisc\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eTrim\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e2016-2018\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eFocus\u003c\/td\u003e\n\u003ctd\u003eRS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eGIRA2-169\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGiroDisc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePosition\u003c\/td\u003e\n\u003ctd\u003eRear (pair)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRotor Type\u003c\/td\u003e\n\u003ctd\u003e2-piece fully floating, slotted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHat Material\u003c\/td\u003e\n\u003ctd\u003e6061-T6 Aircraft Spec Aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisc Material\u003c\/td\u003e\n\u003ctd\u003eProprietary cast iron (USA-sourced and machined)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrive Pins\u003c\/td\u003e\n\u003ctd\u003e10x high-strength alloy steel, cadmium plated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMount Style\u003c\/td\u003e\n\u003ctd\u003eFully floating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eSold per pair (both rear rotors)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Manufacture\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e2x GiroDisc GIRA2-169 2-piece rear brake rotors (complete pair)\u003c\/li\u003e\n\u003cli\u003eDrive pins pre-installed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAbout GiroDisc\u003c\/h4\u003e\n\u003cp\u003eGiroDisc designs, manufactures, and sells 2-piece fully floating brake rotors from their facility in the United States. Every rotor is produced entirely in-house using US-sourced materials, from raw iron poured in their own foundry to final machining and assembly. GiroDisc products are trusted by professional racing teams and track day enthusiasts who demand consistent brake performance under sustained high-temperature conditions.\u003c\/p\u003e\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eWhat years does the GIRA2-169 fit the Ford Focus RS?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe GIRA2-169 fits the Ford Focus RS Mk3 produced from 2016 through 2018. The Mk3 Focus RS was only sold in the US for these three model years. Confirm your Focus RS is the third-generation RS before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the advantage of a 2-piece floating rotor over a conventional one-piece rotor on the Focus RS?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA conventional one-piece rotor expands as a single unit when heated, creating internal stress that can cause warping and pedal pulsation. The GIRA2-169's floating design allows the iron disc to expand independently of the aluminum hat, eliminating thermally induced distortion during sustained track use. The aluminum hat also significantly reduces unsprung weight compared to a full cast iron one-piece rotor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill the GIRA2-169 work with the stock Focus RS rear brake calipers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The GIRA2-169 is a direct bolt-on replacement that bolts to the OEM Focus RS hub and works with the factory rear brake calipers. No caliper modifications, spacers, or adapters are required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre GIRA2-169 rotors street legal?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. GiroDisc 2-piece rotors are street legal and work equally well for daily driving and track use. They are quiet, produce no additional vibration on the street, and function normally with any approved brake pad compound.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo GiroDisc rear rotors require a break-in procedure?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. GiroDisc recommends a bedding procedure to properly transfer pad material to the rotor surface. Perform 8-10 moderate stops from 60 mph to 10 mph, avoiding complete stops, then allow the brakes to cool. Follow with 3-4 more aggressive stops from 80 mph. This procedure seats the pad and rotor surfaces for consistent performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use any brake pad with the GIRA2-169?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The GIRA2-169 is compatible with any brake pad compound including OEM, street performance, and track-compound pads. For track use, match the pad compound to the expected brake temperature range for best performance and longevity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the warranty on GiroDisc GIRA2-169 rotors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eGiroDisc stands behind their rotors against defects in materials and workmanship. Contact GiroDisc directly for specific warranty terms applicable to the GIRA2-169. The rotor rings are a wear item and are replaceable separately if the ring wears out before the hat, extending the overall service life and reducing replacement cost.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the GIRA2-169 replacement rings available separately?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. GiroDisc sells replacement rotor rings separately, which means when the iron disc surface is worn you only need to replace the rings rather than the full 2-piece assembly. This significantly reduces long-term operating costs compared to replacing full one-piece rotors.\u003c\/p\u003e\n\u003ch4\u003eInstallation Overview\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eSafely lift and support the vehicle, remove the rear wheels\u003c\/li\u003e\n\u003cli\u003eRemove rear brake calipers and caliper brackets, hang with wire to avoid strain on brake lines\u003c\/li\u003e\n\u003cli\u003eRemove the OEM rear rotors from the hub\u003c\/li\u003e\n\u003cli\u003eInstall the GIRA2-169 GiroDisc onto the rear hub, aligning bolt holes\u003c\/li\u003e\n\u003cli\u003eReinstall caliper brackets and calipers, torque all bolts to factory specification\u003c\/li\u003e\n\u003cli\u003eReinstall wheels and lower the vehicle\u003c\/li\u003e\n\u003cli\u003ePerform the GiroDisc bedding procedure: 8-10 moderate stops from 60 mph, cool, then 3-4 more aggressive stops\u003c\/li\u003e\n\u003cli\u003eAllow full cool-down before resuming normal driving or track use\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead and phthalates, which are known to the State of California to cause cancer and reproductive harm.
