I took a look under my car this weekend. I saw the anti-sway bar. Is the stock anti-sway bar on the Civic LX hollow?
I had an Accord that I changed out the sway bar. The OEM Accord anti-sway bar was light and hollow and flimsy.
The reason I am asking is if it's worth changing it for better anti-sway effect. The bushing on the end links and bar holder are rubber, but I think that changing those to polyurethane isn't going to make a difference if the sway bar is weak.
