You don't need a whole rotor. These Giro Disc 380mm front replacement rings bolt onto your existing GiroDisc hats. That is the lowest-cost way to keep a track-driven G8X stopping like new, season after season.\u003c\/p\u003e\u003ch3\u003eSame rings as a new GiroDisc rotor\u003c\/h3\u003e\u003cp\u003eThe rings are the same parts GiroDisc fits to its complete G8X front rotor (A1-282). The high-carbon iron casting is made to GiroDisc's own spec, and its 72 curved vanes compare with 30 in the factory disc, which pulls more cooling air through the ring under hard braking. Slots keep the pad face fresh and the bite consistent from the first stop to the last lap. Each ring comes with new floating hardware, so the rebuilt rotor floats and centers itself just like a new assembly.\u003c\/p\u003e\u003ch3\u003eWhen to replace\u003c\/h3\u003e\u003cp\u003eReplace the rings when they reach the 34mm minimum thickness, or sooner if a crack reaches the outer edge of the ring. Swapping rings on the bench takes far less time than buying and shipping complete rotors, and the hats can be reused for years.\u003c\/p\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cp\u003eTwo front rings plus new mounting hardware.
