Does it make a big difference?

Which are the best for an 06 accord v6 6sp sedan

 

i have a 95 and I added a rear sway bar. It made a noticeable difference. If you car doesn't have one then I suggest you get one. Changing the front would be more or less futile in my satiation because I have one. The aftermarket replacements are the same size as the EX units. All one really needs is to replace the busings with some stiff urethane and that should suffice.

Since your car is relatively new, I think the front sway bar would be fine. In my case the EX front sway bar is larger than the LX, and adding urethane bushings is the probably the best option. A front adjustable sway bar would be overkill for a street ride. As for the rear, if you don't have one then get an aftermarket replacement. A swaybar in the rear will cause the back end of the car to slide out in a turn, more like a RWD application. A stiffer front causes the front to slide first. I prefer the rear to get loose before the front.
