strut bar/sway bar?

whats the difference between strut bar and sway bar?

A strut bar ties itogether the tops of your struts, and a sway bar ties together your lower control arms. Strut bars can be installed in a few mintutes, sway bars require a little more time.

I have a strut bar already. Do the sway bars go on the bottom of the suspension?

Yes, for the most part.

A rear sway bar on a FF Honda is one of the best ways to improve handling. It took my Civic from bad understeer to snappy oversteer. Awesome.
