Why do I need adjustable lowers?

[307 Regal]

If I already had a set of adjustable upper control arms, why would I need a set of adjustable lower control arms? I know adjustable uppers can help reduce wheel hop by changing pinion angle but what specific advantages to adjustable lowers provide? :?:

I think I figured it out.

Well I decided to jump on UMI's Christmas sale and I couldn't decide which lower control arms I wanted. I decided to go with a non-adjustable polyurethane/"roto joint" combo since I was getting adjustable uppers. Got some sway bars as well. Hopefully it all shows up soon..
