The slotted face and curved vane design pump air through the rotor for consistent cooling under repeated hard braking, while the floating mount system on rotor A2-152 allows the disc to expand and contract independently of the hat to reduce warping.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-piece floating design separates the aluminum hat from

GiroDisc\u003c\/h4\u003e\n\u003cp\u003eGiroDisc manufactures two-piece racing and off-highway brake rotors in the USA, building floating rotor assemblies like the A2-152 used by road racing, time attack, and track day enthusiasts who need consistent braking performance under sustained heat.\u003c\/p\u003e\n\u003ch4\u003eFAQ\u003c\/h4\u003e\n\u003cstrong\u003eWhat is the A2-152?\u003c\/strong\u003e\n\u003cp\u003eIt is the manufacturer part number for the GiroDisc slotted rear rotor pair built for the Audi TT RS (8J).\u003c\/p\u003e\n\u003cstrong\u003eWhich Audi TT RS years does this rotor fit?\u003c\/strong\u003e\n\u003cp\u003eIt is built for the 2010 through 2013 Audi TT RS (8J).\u003c\/p\u003e\n\u003cstrong\u003eIs this a front or rear rotor?\u003c\/strong\u003e\n\u003cp\u003eThis is a rear rotor, sold as a pair for both sides of the rear axle.\u003c\/p\u003e\n\u003cstrong\u003eDo I need different calipers to run this rotor?\u003c\/strong\u003e\n\u003cp\u003eNo. It is designed to work with the factory OE calipers with no modification required.\u003c\/p\u003e\n\u003cstrong\u003eWhat is the hat made from?\u003c\/strong\u003e\n\u003cp\u003eThe hat is machined from US-sourced 6061-T6 aircraft specification aluminum.\u003c\/p\u003e\n\u003cstrong\u003eWhat is the disc face made from?\u003c\/strong\u003e\n\u003cp\u003eThe disc face is a proprietary cast iron formulation poured in the USA and machined in-house by GiroDisc.\u003c\/p\u003e\n\u003cstrong\u003eWhy is this a
