here ya go...
If you were to stand directly behind or in front of one of your tires to view its vertical angle, you would be looking at its camber. Actually, camber is most often set between 0 and -2 degrees, so you'd be hard pressed to see any lean at all. Negative camber refers to a wheel that is leaning inward with its top closer to the vehicle than its bottom. Positive camber, surprise-surprise, is the opposite, and means that a wheel leans out with its top further from the vehicle than its bottom. Many of the original Volkswagen Beetles had noticeable negative camber in the rear tires which made them look like they were squatting all of the time. A slight amount of negative camber setting is desirable because as a vehicle turns the outside wheels get pushed into a more positive camber state. This results in a camber of zero, or a straight up-and-down wheel, while cornering, which provides the largest contact patch and the greatest traction for handling.
