That's not really true about all of them only being able to be installed in one position. It totally depends on the built in clocking of the bar. On a lot of bars you can actually get to two different install locations. One with the LCA's all the way down, the other with the LCA lifted up. On a car that's lowered significantly, there can be benefits to installing the bars with the LCA's lifted up above ride height. Then the adjusters are screwed most of the way in at the lowered ride height, instead of hanging all the way out of the LCA's.
The other thing is that if you use tubular LCA's the LCA never hits the K frame. So the LCA will literally hang straight down. Needless to say, if you install the bars with the LCA near that location, you'll be riding round like a 4x4 even with the adjusters backed all the way out.
