Camber is the angle that both front wheels are tilted at the top and bottom as they roll down the road. This is negative camber, measured in degrees. The top of the tire is pointed in and the bottom is pointed out. Negative camber keeps good tire contact patch on the road in turns. Mustangs do well with 1/4-degree to 1-1/4-degrees. For street use, 1/4 degree of negative camber is best. For road racing, you may want a pinch more negative camber.
