No, you don't want a Fidanza flywheel, believe me. They're too light for normal driving; too small of a rotational mass, not enough stored energy for bellow 2000 rpm from start launches. Those light-weight flywheels are for launches on a drag strip, say about 4000 rpms and such. You don't want to have to rev up your car every time to 4000 just to start from a light, believe me. IF and when I get my 12.5 lb. flywheel in my DA, I can let you drive it to see how it is. 12.5 lbs. is the least I would go. I am even thinking about stock.
