I wish it was just that simple.the weight and the dampener all play together in the design of the engine Mercedes built.taking a few lbs away could potentially do damage to the seals and the bearings as the stock system was built with everything g playing together under all conditions and loads in the engine.

back in the day with my e36 m3 I had a 10lb light weight flywheel that got rid of the double clutch plate and needed a spring clutch to get rid of chatter in nutrol with the clutch not pushed in.

I kept the stock clutch and had turner Motorsports do underdrive pullies and I wanted the un Orthodox crank pulley and they said with my setup alot of guys had engine issues with spinning the oil pump nut off from the harmonics being off and added vibrations was just a bad idea to run the crank pulley with a lightweight flywheel.

we ended up doing all the accessorie pullies to accomplish the same affect and left the crank pulley alone and I put over 100k miles on my m3 and beat the living crap out of it while others were spinning bearings and damaging there cars in less then 10k miles.
