Should I get the Stillen Adjustable Upper Arms to fix this problem first? I also know for a fact that my shocks are not good as if you push down the car or lift it up, no matter what corner you do it, it won't go back to the original place but stay there for a while.. then it goes back slowly... springs I think are ok, but if I'm doing the job, lets just do everything in one shot... I wanted to lower the car anyways... what do you think?
