it doesnt really do anything accerleration wise except maybe in first gear, otherwise the load of the car and transmission are to much to notice a difference in a lighter flywheel. The main difference is when you shift. Having the absolute lightest flywheel possible isnt nessisarily good. Its the same as sway bars. You need to find the right one that fits you and your car. The lighter the flywheel the faster the revs will fall inbetween shifts. And the quicker it will raise when you tap the gas to downshift.
