The car being light doesn't necessarily help stop the wheels from lockng, if anything, with there being less weight pushing down on each tyre, the problem cold actually be worse. I agree that as long as the bias is adjusted to send most of the braking effort to the front wheels then there won't be any involuntary "handbrake turns", but what I am looking at is ways of geting the rear wheels to do their share of the braking, up to the point at which they would lock if ABS was not fitted.
