Just wondering if competition rigs will ever try to incorporate some
type of active weight bias where they can move some type of weight
around the vehicle.
Kinda like some of the fathers that started using the moving ball ballast
on the pinewood derby cars.
Will we see it? More complication, but who knows……..

sittin around the shop we have engineer one that uses ballast tanks and mercury. you just pump the mercury into the need corner for an additional 200 lbs of ballest.
fyi back some years ago i was on a movie set and the movie camera crane they were using used exactly the same method to counter balance the weight of a man on the end of the boom.

It's funny, I was just thinking about this last night. I was thinking that you could use anti-freeze.

Both mercury and antifreeze sound like an environmental mess waiting to happen. Probably safer to use a non-toxic liquid, or something solid.

active weight bias is old technology. That is what spotters were doing before they stopped letting them touch the rigs.

Mercury is the way to go. I can't see why Glycol? (antifreeze). Mercury is over 150 lbs per gallon and glycol is about 9.12 lbs per gallon.

I don't think it will catch on. With a system like this you going to need to add 200 lbs worth of movable balist plus the weight of the system to move the weight. It's just too much extra weight. Active suspension shocks would acomplish the same goal with far less weight.

Yep, but Propylene Glycol is probably much cheaper:D
Didn't BMW have that in the GT M3's? about 400lbs that move quickly to provide weight during cornering, accle and breaking???
