The adjustable examples you show do not go along with what I think Bret was talking about. They are made that way to allow adjustability to make camber adjustment possible where there was none from the factory. The bent ones allow clearance around other suspension components or the frame in instances where the car was lowered. I believe what Bret envisioned was having inner mounting points for the upper control arms made to slide up or down on the frame through the use of a screw actuator or a hydraulic mechanism of some sort which could possibly give you the stance you want when the car was at rest, while allowing the upper arms to be mechanically put back into the proper, original position with the car raised for driving. What you are asking for is much more complicated than your examples seem to point to.
