There seem to be a lot of theories on what weight flywheel works best in these cars. I like the one that these cars are pretty light so there's no need for a 30 or 40 lb flywheel. But you may not be happy with a 12 or 13 lb one either in street driving. So, sort of like Goldilocks and the 3 bears, a medium weight flywheel in the 20 - 25 lb range must be just right. My 1-1/2 cents of questionable opinion anyway.
