Got an AWE Stage 2, 12 or 14# aluminum flywheel with a spoked clutch disc. Works well, it is a bit easier to dump, but only rarely. The clutch engagement isn't as grippy as I'd expect, but it does hold well for occasional launches and power shifts.
I recently got a lightweight fly and stage 2 spec clutch. Im waiting to get it back from Spec to be resurfaced (got it used) and ill probably get it installed next weekend. ill ill post up once i get it all done.
I'd be interested to know this too... one of my main gripes about the car is the very very heavy stock flywheel. It helps the car hold RPM's nicely, but almost annoyingly so. It seems to be too heavy for the car. Those Germans love heavy flywheels though, as it has been a common gripe of mine for almost all of the German cars I have owned.
In all honesty, if I had to do it over again, I might do it differently. I was mainly concerned with drivability. That's what drove my decision. I like the quiet, rock-solid, vibration-free idle. However, it's become clear that there IS a price to pay in terms of power delivery, not only because of the weight but because of how the dual-mass flywheel "absorbs" torque.
