I am going to get the TL-S and was wondering if I should get the sway bars when I buy it. I know that the the rear sway bar is supposedly thicker in the TL-S, but will that be sufficient...I know no one really knows, but does anyone have a guess?

Also, I want the tighter cornering and handling, but do NOT want to sacrafice the smooth ride and road noise....will the Sway Bars affect any of that? Please advise

 

You're right -- you won't know if you want the rear sway bar until you drive the TL-S with the stock one.

One thing to keep in mind is that although sway bars can have a positive effect on handling, they serve to make the suspension on either side of the car less independent (by connecting the right rear and left rear wheels with a larger sway bar, you're effectively making them more like one unit rather than two independent ones) and may therefore sacrifice some ride quality. It all depends on what you value more.

Just to be anal, they are actually referred to as anti-roll bars.
