Go to the suspension board and ask this question.

 

From what I've heard you don't really need them, but once you put them on you'll be really glad you did. I've heard they make the car feel a lot more solid, not to mention the SFCs supposedly get rid of some of the squeaks and rattles our cars are known for.
