Any time you change the centerline of the tire location relative to the steering axis inclination angle, it changes the scrub radius. Same if you put different offset wheels on. Also, changing the centerline of the wheel to the centerline on the spindle changes how the loads are placed on the bearing, in this case, it shifts it further towards the smaller outer bearing.
Now, if you installed wheels that compensate for the thickness of the spacer, and puts the wheel centerline back where it should be, like when dealing with the duallie wheels used on the extended hubs, then that would be fine. But with stock offset or negative offset wheels, it would be an issue.
