How do I improve my Ford Focus suspension?

I recently purchased a used Ford Focus and noticed that the suspension feels a bit rough. What are some ways I can improve the suspension for a smoother ride?

Firstly, make sure to check the tire pressure regularly as it can greatly affect the suspension. Also, consider replacing the shocks and struts if they are worn out. Upgrading to a higher quality suspension system can also improve the ride quality.

Another area to check is the suspension bushings. If they are worn out, they can cause the suspension to feel rough and unstable. Replacing them with new ones can make a noticeable difference.
