This is true when racing on straight-ramp tracks with tight transitions, e.g. BestTrack. On curve-ramp tracks, e.g. Cub Scout Leader's HOW TO Book, Piantedosi, and Freedom, the difference gets lost in the noise.

WOW! What else do your district's best performers buy?

If it is the later, I don't think this rule will help. The people that win with your current rules will win with your new one.
Quite likely, but not because they used tungsten as ballast!
I suspect Stan's rule would change nothing. Once a District allows other than a 4 3/8" wheelbase, using slots, a whole lot changes.
I think that it changes the thought process leading up to building. And it changes the "up front" costs for first time racers. It "pulls them into the hobby" more gradually, and makes their entry more about knowledge and less about $.

First, the cost is "up front". Second, I don't like to sacrifice my car from last year in order to build my car for this year.

No matter what was used for weight they were limited on the amount that could be added. My scouts had an advantage before the pin dropped - OK, except for the one little Hot Rod that beat us since we all raced the Bear class.
That advantage was partly due to knowledge and effort put into the build (Yay!) and partly due to buying high density (Boo!).

What? The 2.x and 1.x gram wheels that a lot of folks purchase are prepared on a lathe! The "Wheel Shaver" used to true wheels operates on the fundamentals of a lathe. Spinning a wheel using a hand-held drill and holding a block of sandpaper against the tread is a lathe process. All legal in most districts. The results are the same; just the details of how they got that way are changed.
Or are you talking about some of the "fancy tread profiles" that are possible on a lathe?
