Your springs control ride height. If the bushing was worn the strut would just lenghten or shorten to compensate but the ride height would be controled by the springs.
As you move the strut won't it change length to compensate for the angle. The strut won't pick up the vehicle or let it lower because the spring is supporting the vehicle weight and controlling ride height. I can't believe you could have that much adjustment for camber or caster to affect ride height 1/4" but maybe I'm wrong?
