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.
Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration.
