034Motorsport 2-Piece 380mm Floating Front Brake Rotor Upgrade for BMW F8x M2/M3/M4

This kit replaces the front brake rotors on the BMW F8x M2, M3 and M4 with 380 x 30mm two-piece floating rotors designed to work with the factory front calipers. 034Motorsport quotes about 23.8lbs per rotor, 0.2lbs less than the 24.0lbs factory rotor, while keeping enough thermal mass in the ring to absorb and shed heat. Each rotor combines a 6061-T6 aluminium hat with a CM-250 alloy ring on high-strength alloy steel bobbins, uses 72 directionally curved vanes for cooling, and has a J-slotted face that cleans the pads with less noise than a conventional slotted rotor. The rings can be replaced on their own, and the brand puts installation at 2 to 3 hours.
