One of the biggest issues is the lightweight flywheel itself, we have seen some that were several grams out of balance themselves right out of the box. That could be corrected by having whoever does your engine balancing spin it up and correct the imbalance (including the new clutch assembly), but not everyone does that, and ultimately pays the price.
Proceed at your own risk.

It's an endurance race car -- he won't know what killed it when it does die :-)
I have a SPB and a ChampCar with an AASCO.
Also had a Boxster S drive to the track car with an AASCO, about 10k track miles on that setup. Sold it a few years back -- still going strong as best I know.
YMMV,
