It only increases the leverage on the bearings, etc. There is nothing say it WILL break, but only increases the potential -- there's no getting around that. Instead of pushing straight down on the bearings (as with a 0 offset and 0 camber), the bearings are being pulled at the bottom and pushed at the top harder in a direction they weren't designed for (kinda), while the studs are being pulled while at the bottom (maybe the top, too, and they keep rotating so forces pull in, out, in, out... or maybe this is going beyond my understanding).
To be more accurate, the bearings, because they sit further inboard than the studs, are always being leveraged upon rather than getting a straight vertical force applied to them.
The forces exerted are likely well within tolerances.
