Thanks, Razibilla, but I'm not sure about the legend part, more of an inveterate tinkerer - my Trabant is a recent acquisition and one of the first things (after moving the driver seat rails back 5 inches) I did was start poking around on how to get rid of the positive camber which, unless you are the left front wheel on a NASCAR car, is one of the most vile handling suspensions you can have. Driving around town or in a straight line it is no big deal, but the reality is that you are really driving around with the weight mainly on the outside half of the tire tread. If you have to make an emergency move or just get sporty you load up the wheels on the outside of the turn (e.g., the right side in a left turn), and in particular the rear wheels as the positive camber will get more positive. Of course, this is the wheel you want to have the most grip in this sort of maneuver. With all the positive camber in a (for example) sporty left turn, what happens to the right rear is that it will actually tend to tuck under which will put you way out on the edge of the tire (which is skinny enough to start with) and overload the sidewall which, as you can imagine, might make the sporty turn more sporty than intended. Getting the camber to neutral will tend to eliminate this problem, but a couple of degrees of negative camber is preferable. In the case we have the opposite of the above, driving in a straight line or around town you are on the inside part of the tread, but in our sporty left turn as the right rear is loaded, the negative camber becomes less negative as the wheel becomes more perpendicular to the pavement which means you actually have more tread in contact, more grip, and less chance the back of the car is going to swap ends with the front.
