Welcome to the forum.
"Best Suspension" for what? Street driving? AutoX? Drifting? Because different setups will work "best" for each category...
There is tons of great info in the suspension section.

I went with Eibach Pro Kit springs. They work well with stock shocks, are inexpensive ($239), and there is a great DIY (in in the DIY section) that was easy to follow. I DD my car. The springs lowered my car a modest 7/8" and are only slightly stiffer. I like them.
Good Luck!
