What is the point of making both the upper and lower A-arms adjustable?   
It's true that on some cars, it would be advantageous to have the upper A-arm 
be a bit longer.   The adjustable ones were designed to accomodate that 
desire, but nobody really adjusts them on a routine basis.   They just set them 
to a length slightly longer than stock, while the car is being aligned, and 
then that's it.   $600 (or whatever) gets flushed down the tubes to provide 
adjustment you don't need.

On the other hand, fixed-length A-arms that are longer than stock are 
available.   This actually solves the problem in a simple, elegant fashion.   You 
just unbolt your stock A-arm, swap the ball joint over to your new, longer 
one, then have the wheels aligned normally.   It's just that simple, and 
half the cost of the adjustable versions.   Both get you to exactly the same 
place; one does so with much greater simplicity for half the cost.
