Description
The 034Motorsport 2-Piece Floating Front Brake Rotor Upgrade Kit for the BMW F8x M2/M3/M4 is a complete replacement 380mmx30mm brake rotor kit, designed to work flawlessly with the factory front calipers found on the BMW F8x M2/M3/M4.
Weighing in at approximately 23.8lbs, each rotor reduces rotational weight by 0.2lbs on each corner over the factory 24.0lbs rotors. While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture, and dissipate heat
The 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 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.
The face of the 034Motorsport 2-Piece Floating Front Brake Rotor Upgrade Kit 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.
The 034Motorsport rotor and hat floating mount system 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.
