Simply because the new upper arms are longer than stock (with any lift kit availablefor the Xterra).

In stock form, the camber angle actually decreases while cornering. Nissan spec 0.1-1.1 degrees at static height. During cornering, the outside tire stays perpendicular to the ground as the suspension compresses.
With longer aftermarket arms, the top of the tire is forced outward instead, reducing the contact patch and causing wear on the outside edge of the tire.
To remedy this, the camber spec is changed to allow some negative camber at static height.
