I did Global West Delrin Control arm bushings, poly bushings in the sway bar, Steeda x2 ball joints along with stock control arms and QA1 coiloversBump steer kit is a waste for 99% of us. Small stuff like bushings will really only be noticed if the current stuff if bad or wore out. I did poly sway bar bushings and didn't really notice a big difference. Even though one was so bad it was clunking. I did notice a difference going to solid steering rack bushings, but my originals had 100k.
I wouldn't bother with control arms. Especially if you're staying with the stock spring location.
