Upgrading your front rotors will increase overall braking performance in street, track, and HDPE driving conditions, as they keep your brakes cool and strong all day long!\u003cbr\u003e\u003cbr\u003eWeighing in at approximately 25.0lbs, each rotor reduces rotational weight by 3.1lbs on each corner over the factory 28.10lb rotors! While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture, and dissipate heat.\u003cbr\u003e\u003cbr\u003eThe central hat portion of the 034Motorsport rotor is made of 6061-T6 aircraft specification aluminum. The disc is constructed out of a proprietary metal alloy that can withstand immense braking temperatures while holding form. The rotor utilizes 48 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.\u003cbr\u003e\u003cbr\u003eThe face of the rotor utilizes J-Slot slots to clean the pad and surface of contaminants and allows hot pad outgassing, all while reducing overall braking noise compared to a traditional slotted rotor.\u003cbr\u003e\u003cbr\u003eThe rotor and hat have a floating mount system that utilizes high strength alloy steel bobbins. The pins take the load from braking actions while maintaining the axial and radial float between the hat and disc, allowing for safe expansion and contraction from heat.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLightweight Construction (\u003cstrong\u003e25.0lb\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e034Motorsport Rotor vs.\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e28.0lb\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eOE BMW Rotor)\u003c\/li\u003e\n\u003cli\u003eFloating, 2-Piece Design\u003c\/li\u003e\n\u003cli\u003eAerospace Grade Aluminum Hats\u003c\/li\u003e\n\u003cli\u003eCM-250 Special Alloy Rotor Rings\u003c\/li\u003e\n\u003cli\u003eJ-slotted Friction Face\u003c\/li\u003e\n\u003cli\u003eOEM Fitment \u0026amp; Functionality\u003c\/li\u003e\n\u003cli\u003e48 Curved Vanes Force Cooling Air through Brake Disc\u003c\/li\u003e\n\u003cli\u003eFloating Bobbins Mounting System\u003c\/li\u003e\n\u003cli\u003eReplaceable Rotor Rings\u003c\/li\u003e\n\u003cli\u003eLower Long-term Maintenance Cost\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOE Part Interchange:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e34 10 8 858 705 (Left)\u003c\/li\u003e\n\u003cli\u003e34 10 8 858 706 (Right)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's Included:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e348x36 Left Rotor\u003c\/li\u003e\n\u003cli\u003e348x36 Right Rotor\u003c\/li\u003e\n\u003cli\u003eInstallation and Break-in Instruction Sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ci\u003e**Please Note: Type III hard anodizing of aluminum is considered as a functional surface coating process.
