I had the same problem when i installed my coilovers and lowered it, i tried a whiteline swaybar with adjustable drop links thinking it would fix the problem, but it was just as bad.
I'm not running a sway bar at the moment and it's not TOO bad, but im not the biggest fan.
If it bothers you too, i'd go a Hotchkis front and rear sway bar, they do go under the driveshaft so there shouldn't be any problems
