I've noticed recently, a squeaking noise coming from the rear right of my car on bumps. I have a feeling the suspension is going bad. I am looking at buying new springs and shocks. I wanted to lower the car anyway. What are good combinations of sprins and shocks. I am probalbly getting Tein springs or Eibach. But, I don't know alot about shocks. Any feedback is greatly appreciated.
