Thoughts on lightened ring gears?

[CMcAllister]

Weight is weight. Lighter is better; faster or allows the weight you have to carry to be put where it is most beneficial. Dollars per pound reduction from the car is a consideration. Sprung vs. unsprung. Steel vs. aluminum vs. titanium. Mild Steel vs. Chrome-Moly. Fiberglass vs. carbon. The old expression is - The best way to save 100 pounds is find 100 places to remove a pound.

What about the lightweight transmission parts?

When I ran my 68 Impala 396/325 stick car I initially ran a standard gear, after 17 passes those blew up. Switched to Pro Gear lasted up to 100 passes in that car, same set and rear in my 65 Impala stick I will be running.

Pro gears definitely! Of course, no matter what you do, the clutch you run and how you set it up has to be part of the conversation

way back about 15 years ago I did some back to back testing between 1.82 and 1.76 planetary and the 1.76 lost almost a dime in my 10. second V-6 powered Gen 3 Camaro.
how much was due to the .06 in gear ratio?? not sure. My thought was weight of the rotating mass. It didn't pull of the gear change as quick..
I've always thought about building a 1.82 alloy planetary.

With the quality of the ring and pinions, and the weight of your car, ( ie not a comp car) doubt its worth the risk....jus sayin

OK, so the consensus is that lightened ring gears are not of any value. How does everyone feel about the other available ring and pinion treatments, cryo, shot-peening and micro-polishing (which MW calls Supra-Fin)? I'm going to make a gear change before spring, and think I'll opt for cryo treatment, but that will be it. Any strong evidence to change my plan?

Most are shoot penned in production at some phase.
