Flywheel origin question..
I replaced the clutch/flywheel combo in my '02 Coupe this weekend, with a Monster Stage 2 kit & 18lbs flywheel.
While I had the components out, I decided to weigh the flywheels for comparison.
The Monster billet came in at 18.5 (including the ring-gear.)
The OEM came in at a surprising 22.5lbs!
I was under the impression that OEM flywheels were 28lbs..? Factory lightened unit?
Any clues on what kind of flywheel I may have? It's cast and has GM cast into it. I'm considering keeping it for another LS build if it is indeed a factory light-weight unit.
Just want to know if it's worth storing..
Thanks!

The flywheel also doesn't have any obvious machining marks on the front or back of it, so I don't think it was lightened after production. The back has the obviously look of casting and I think the stack height would have been incorrect if it had material removed from the front.
I may have just kept the OE flywheel if I knew it was already lighter than expected.
My curiosity is still eager for an answer..
