How to Adjust Panhard Bar?

[dmw319]

So I am installing my 3" rear/1" front drop springs and shocks (w/relocation brackets) from ECE this week and an adjustable panhard bar with new bushings since mine was shot I figured I might as well upgrade the whole bar.

Question, do I install the bar along with my springs/shocks and THEN adjust it? Or do I wait until after I install the other components and let the suspension settle and THEN install it? And is there any science to adjusting it other than making it the proper length and bolting it on?

Thanks in advance!
