Lighter flywheel do nothing in regards to vibration, all the flywheel does is smooth out the engine output by storing energy. The engine doesnt produce a stable constant output, its rather in pulses, each explosion in a cylinder is a pulse of energythat goes down your drivetrain. A lighter flywheel will let your engine rev faster as well, but this time with a much more dramatic inpact than the pulley. While you may save 1 or 2 lbs on the crank pulley, you can save over 10lbs on the flywheel. I have a ACT flywheel which is around 11lbs lighter than stock (I think), and the engine does rev up and down much faster than before. It doesnt make the car any quicker, it makes hill starts a bit harder, but it also makes rev-matching a lot easier, which is what I wanted out of it (as well as a few lbs of the car's curb weight). There isnt any real danger that I know of to get a lightweight flywheel for this car (cannot confirm or deny the same for the crank pulley). |

Best crank pulley is a fluidampr, which is heavier than stock.

I hear underdrive damages the alternator. Could just be a rumor though.
