The 034 Motorsport 370mmx24mm 2-Piece Floating Rear Brake Disc Upgrade Kit for the BMW F8x M2/M3/M4 is the ultimate replacement brake disc kit, designed for optimal performance in conjunction with the factory brake calipers of the BMW F8x M2/M3/M4 . Manufactured to meet the demands of both street and track use, these high-performance brake discs provide reliability and consistent stopping power when you need it most. Weighing in at approximately 9.3kg, this lightweight disc benefits from improved thermal mass, allowing it to retain heat effectively. The 36 directional vanes are designed to circulate cooling air through the disc, resulting in efficient heat dissipation. This reduces the risk of fade and guarantees excellent braking response, even under severe conditions. The centre hat of the brake disc is machined from 6061-T6 aircraft aluminium, while the disc itself is made from a special metal alloy designed to withstand extremely high braking temperatures. This allows the disc to maintain its shape, which is crucial for both daily driving and intensive track days. With the 034 Motorsport brake discs, you can enjoy the freedom of riding without the hassle of constant maintenance. The J-Slot design technology not only helps clean the brake pads and remove contaminants, but also promotes gas evacuation from the pads, resulting in less noise compared to traditional drilled discs. Furthermore, the floating mounting system, which uses high-strength steel alloys, provides a secure and controlled clearance between the hat and the disc, optimizing expansion and contraction due to heat.
