The 034 Motorsport 2-Piece Floating Front Brake Rotor Upgrade Kit for the BMW F8x M2/M3/M4 is a complete replacement kit of 380mmx30mm brake discs, designed to work perfectly with the factory brake calipers of the BMW F8x M2/M3/M4Weighing approximately 23.8 lbs, each disc reduces rotational weight by 0.2 lbs per corner compared to the factory 24.0 lbs discs. While reducing weight, the disc maintains the correct thermal mass in the rings to retain and dissipate sufficient heat. The center shield of the 034Motorsport disc is made of 6061-T6 aircraft-grade aluminum. The disc is constructed from a special metal alloy that can withstand enormous braking temperatures without losing its shape. The disc utilizes 72 directionally curved vanes to force cool air through the disc and dissipate heat. The front of the 034Motorsport 2-Piece Floating Front Brake Disc Upgrade Kit uses J-Slot slots to clean the brake pad and surface of contaminants and allows for outgassing of hot brake pads while reducing overall brake noise compared to a traditional slotted disc. floating mounting system The 034Motorsport disc and cap are made of high-quality alloy steel. The pins absorb the braking loads while maintaining axial and radial clearance between the cap and the disc, allowing for safe expansion and contraction due to heat.
