Has anyone tried them or use them?

I don't know about that particular set of anti-sway bars, but yes, many here have installed either the factory parts, Eibachs, etc and love them. They help to eliminate body/chassis flex in cornering and generally tighten up the handling of the car. If you're looking to make your car corner really well then you should consider something like this to go along with lowering springs and better shocks/struts.

I really just consirdering things for better handling.

I have the factory bars now.
