0 camber does not = more tire contact.
Maybe in a straight line it does. But not in a corner where it matters.
As you corner the tire will deform. If you have zero camber, the contact patch will go from being the entire width of the tire to just the outside edge and will give you uneven wear. With added negative camber, as the tire deforms, the contact patch is even across the width of the tire. Maximizing grip and producing even wear.

All cars are intended/engineered to run some amount of negative camber. The weight of the car shifts and tires roll as you turn, so the contact patch is never constant. Cars are designed to lean into the negative camber as they turn. Ideally on a GD Impreza (completely disregarding wheel size and fitment), you want between -1.5 and -2 in the front and -1 to -1.5 in the rear for a good street setup. This won't cause camber wear.
