034Motorsport 2-Piece Floating Front Brake Rotor Kit - BMW M340i (G20) / GR

034Motorsport's front kit replaces the factory one-piece rotors with 348 x 36 mm two-piece floating rotors that work with the stock front calipers. They run cooler and stay consistent through long sessions, and they cut weight at the front, where it matters most for steering and suspension.

What you get

• About 25 lb per rotor, roughly 3.1 lb lighter per corner than the 28.1 lb factory rotor.
• 6061-T6 aluminum hat with a ring made from a proprietary heat-resistant alloy.
• 48 directional curved vanes that push air through the rotor to shed heat.
• J-slotted face that cleans the pad and vents gas, with less noise than conventional slots.
• Uses the factory front calipers, no caliper change needed.

Good to know

• When the rings wear out, replacement ring sets are available, so you keep the hats.
