: Does anyboby know of any lightening options. Is there a supplier for lightened flywheels that will hold up over time?

Just as another datapoint, I'll toss in my experiences here. I had a 13-lb 215mm flywheel attached to my old motor for several-thousand trouble-free miles (mine was done by Top-End) -- not a radical lightening or corresponding increase in rev-ability, but it was nice.
Now, this past summer I put on a 7-lb Tilton aluminum flywheel (and 7 1/4" racing clutch) -- the flywheel and clutch weigh < 10lbs together. This thing *really* revs quickly -- makes gear changes that much faster. Of course, the race clutch can't be used on a street car, but it is way cool.
In neither case did I notice an idle problem. Hope this was useful.
