Mark, it looks like you trimmed down the 911 flywheel and lightened the ring you made. I did almost exactly the same thing, but I bought my ring from KEP.
Yes, the flywheel had about a half inch square "lip"around the OD, this removed a huge amount of rotating mass. Drilling the holes in the adaptor maybe not so much weight, but every bit counts.
The freakin' material that porsche and VW used in their flywheels is hard as hell, some pretty slow going cutting this poop.
Would have been nice to have a spin index to lay out the hole in the adaptor, but I don't have one so I did it oldschool.
