thanks for the input guys. common sense has me thinking i should just resurface the stock flywheel i have and use that, but i really, really want that amazing response and quick revs.
Jason, i haven't forgotten about you. when the time is right in my build i'd still like to have you look over my trans and rebuild the parts that are failing or close. perhaps we can work the price of a light 18lb Diamond flywheel into that.

I have a 12.5lb Fidanza and love it. I also have a heavy'ish car and a decent size cam it's no issue what so ever driving it. To keep the revs between shifts is a simple programming function with throttle follower and throttle cracker tables to where it will keep the IAC valve open allowing more airflow it will not allow the rpms to drop as quickly.

Update, I found a deal on a 3.62 ring and pinion, so those are replacing the factory M5 3.15 gears. Should help the car move out with the lighter flywheel.
I’m shipping my T56 out to Jason tomorrow and will one of his light diamond flywheels while my trans is out there.

Launching!
I have the 18lbs monster unit and its a really nice piece however...i found it easier to drive the car fast on road race circuit with the stock weight flywheel (28.8lbs iirc) because it was smoother...the 18lbs is a good compromise and there is a difference in acceleration but i dont feel its significant.

Yes, 100% positive stock is 23lbs
I wouldn't think the engine efficiency loss w/ a heavier flywheel would really be worth the difference. And to answer the other question, Yes, there are many heavy flywheels made by various places. 25lb, 28lb & 30lb
I use the lightweight fly for most applications and it works great. When looking at rotating weight, you have to look at the weight of the clutch and flywheel. For example, a Diamond kit w/ light flywheel weighs 43lbs and a stock clutch/stock flywheel is 49lbs. 6lbs is barely noticable, as its only 12% less.
