Thoughts on lightened ring gears?

If more folks studied rotational INERTIA more than reading the hype of suppliers of lightweight parts, they would save lots more money. IF one spent more time on reducing the rotational inertia of the flywheel /clutch/converter AND the wheels/tires then there would be a more effective approach. Looking under the streetlight for low hanging performance fruit is cheaper and involves more common sense.Out in the shadows gets more expensive and much more questionable in results.

Yes, nothing in the trans, or rear end, is large enough diameter to have a measurable effect on inertia to show up on your time slip. Hard to imagine how low the hp would be required to see anything on the time slip. Wish I had the time & money back I wasted on parts & track rentals testing, because “there HAS to be something there!”

You are correct, no observable performance improvement from lightweight rearend parts. On the other hand, reduction in weight and diameter of flywheel and clutch made huge performance improvements.
