[Spridgets] Beating a dead horse, or Positive Rear Camber, why not for live axles?

[derf]

I never did get this straight.
If positive rear camber is good for cornering on IRS setups, why
wouldn't it be good on live axles?

I think positive rear camber is good for cornering as you get better
tire contact.  Something like 1/2 to 2 degrees is good, right?  It is
kinda like pre-loading the tires against cornering forces.

Any of you old racers tried such things?
Cheers,
