Anyone run an aluminum flywheel?

The photo I posted above is the RAM aluminum, with a steel insert (where it hits the clutch disk). THis gives the lightness (almost) of all aluminum, yet the longevity of billet steel.
THe holes are merely how they rivet(?) the two compounds together, not for lightening.
Not sure how much lighter the billet all steel one is, but I remember holding both once, and you could tell.

Where did you get it and how much was it if you don't mind?


I saw in an article on the rousch stage III mustang that its flywheel is aluminum...... if they put an aluminum unit of a street car, that might be worth looking into, right?
