Post by: GGR on November 13, 2016, 17:59:05: A lighter flywheel will make quite a difference in the same way lighter wheels do. Some explanations here:

There won't be power gained, but the car will accelerate faster as it it was lighter.

The heavier the car, the less the flywheel should be lightened. For road use, the flywheel can be lightened a bit, but not too much or taking off from a red light may be quite an exercise with the clutch pedal, especially with a taller rear end ratio.
