Its brakes take a beating on track. These Giro Disc 2-piece slotted front rotors replace the factory front discs with a fully floating assembly. That cuts unsprung and rotating mass at the front axle, and the bigger cooling capacity holds up through repeated hard stops. They bolt to the factory calipers with no modifications.\u003c\/p\u003e\u003ch3\u003eWhy a 2-piece rotor\u003c\/h3\u003e\u003cp\u003eA one-piece iron disc is heavy and tends to cone and crack when the friction face gets hotter than the hub. GiroDisc separates the two jobs. The iron ring handles friction and heat. A black-anodized 6061-T6 aluminum hat handles mounting. The ring floats on drive pins, so it can grow with heat without pulling on the hat, and it centers itself between the pads for a consistent pedal. When the rings wear out, you keep the hats and bolt on fresh 380x34mm GiroDisc rings (D1-066), which costs less over time than whole rotors.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHigh-carbon iron rings cast to GiroDisc's own formula for crack resistance under repeated heat cycles\u003c\/li\u003e\n\u003cli\u003e72 curved internal vanes that pump air out through the ring for cooling\u003c\/li\u003e\n\u003cli\u003eSlotted friction face that keeps the pad surface clean and the bite consistent\u003c\/li\u003e\n\u003cli\u003eSpring clips and Belleville washers that let the ring float like a race rotor without rattling when cold on the street\u003c\/li\u003e\n\u003cli\u003eHats, rings and drive pins machined in-house in Bellingham, Washington, from domestically sourced material; cadmium-plated steel drive pins for corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cp\u003eTwo assembled front rotors, one per side, each ring already mounted to its hat.
