[Spridgets] Flywheel needed

Benefit is a quicker response of the throttle (less rotating mass) 
and it sounds great as you go through the gears. Downside is slipping 
the clutch to get the car moving.
I turned my steel one down to 12 lbs. and had it balanced, I think 
the original weight is around 22 lbs. The aluminium ones are for 
racing and not the greatest for street driving especially for the 
stop light at the top of a hill.
With the 12 lb one I don't have a problem with having to slip the 
clutch to get the car moving.
