The factory BMW flywheel is a 2 piece design that mitigates vibration and creates a comfortable driving experience. A single piece aftermarket flywheel will allow the engine to rev quicker and gives shifting a much more direct and mechanical feel. This also makes clutch modulation on spirited takeoffs much easier and more predictable and is a must if you plan on tracking or competing in your BMW.
