In every tunning book we read that sway-bars are fundamental to control car handling.
We did use them on carpet, but why so rarely on asphalt?
Does the rubber tires need so much weight transfer to work?
Does the circuits we run use a "bad" asphalt?
Or can't we scale down the sway-bar thickness to be useful?

It was my understanding that on bumpier tracks you don't use a sway bar. Asphalt not being as smooth as carpet (should be) lessens the effect the sway bar has.
