You can't do the rear sway bar without dropping the rear sub, so while it is down, might as well do the bushings. I would order the whole kit, and not install the front lower control arm bushings until the old ones needed replacing if I wanted to save some labor cost. The bushings can't be that bad to purchase, but they were labor intensive on the install. Down the road when the stock bushings go bad, have the sportline bushings pressed in (maybe store them in a double zip lock bag in a dark place to avoid excess deterioration). Or get the part # for the LLCA bushings and order them down the road if you don't want to store them.
