I noticed that in that site, it illustrates positive camber. The camber that is best for handiling is actually negative camber, not positive. This means that the best handling cars have the bottoms of their wheels/tires extend farther out than the tops. This way, when a car goes around a corner and the car's weight transfers, the entire tire is making contact with the road, as opposed to in no camber, where only the outside edge touches the road. In negative camber the wheel that is making maximum contact with the road also has the weight on it. This is why positive camber is inferior to negative- the tire that makes full contact with the road in positive camber is the one with the weight off of it. Of course, any camber at all reduces the tire's contact with the road in a straight line, reducing both the tire's street life and ability to hook up in a drag.
