Weighing in at approximately 25.0lbs, each rotor reduces rotational weight by 3.1lbs on each corner over the factory 28.10lb rotors! While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture heat, while utilizing 48 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.      \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNVH Levels: None-Low\u003c\/strong\u003e\u003cbr\u003e\u003cimg height=\"63\" width=\"186\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0005\/7773\/2663\/files\/NVH-level-0.5_4b84ff0c-3488-4c80-bec2-3574dae4aa70.jpg?v=1735055032\" alt=\"\"\u003e\u003cbr\u003eNVH is the measurement of how much noise, vibration, \u0026amp; harshness gets transmitted into the cabin of your vehicle. The 034Motorsport 2-Piece Brake Rotors transfer none to low amounts of noise to the cabin based on user feedback. This NVH is relative to the brake pad installed with the brake rotor. Different brake pads will have different resonances when passing over a rotor with slots, which can sometimes make a slight whirring noise. The sounds from these rotors are the direct result of the performance improvements they make to the braking. The J-slots release gas from under the brake pad, and the high-density directional aero veining in the rotors move substantial air, all resulting in more sounds of air moving. The installation of other suspension components can also affect the NVH transferred. NVH is subjective, so some users may find NVH to be increased or decreased from our rating. If you are experiencing higher than quoted NVH with this product, please email \u003ca href=\"mailto:techsupport@034motorsport.com\"\u003etechsupport@034motorsport.com\u003c\/a\u003e for further assistance.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eProduct Description:\u003c\/h3\u003e\n\u003cp\u003eThe 034Motorsport 348mmx36mm 2-Piece Floating Front Brake Rotor Upgrade for BMW G20 M340i and Toyota A90\/91 GR Supra is a complete replacement brake rotor, designed to work flawlessly with the factory front calipers.
