What is the best suspension set-up for a Ford Focus ST?

I recently purchased a Ford Focus ST and I'm looking to improve the handling and performance. What are the best suspension components and set-up for this car?

For the best handling and performance, I would recommend upgrading to a coilover suspension system and adjustable sway bars. This allows for fine tuning of the suspension to fit your specific driving style and needs.

Another key component to consider is upgrading to high-performance shocks and struts. This will not only improve handling but also provide a smoother and more comfortable ride.
