i have a 2009 civic si
and i was thinking of getting a sway bar kit front and back and was wondering if it would help much i have seen people say that strut bars are useless on the newer civics and was wondering is this true ?

 

Just the rear bar made a hell of a difference in my 06Si, I could not believe how well it handled.

If you like driving the twisty roads like I do, you will enjoy it.

Try a rear first pro civic has an eibach for 100, I'm getting one to try on my 12, the measurements look good so I'm going to give it a shot.

 

ok and dose any one know what mm the stock si sway bars are ?
the eibach kit i saw was 32 and 19 i think may be wrong

 

MY o6 was a 19 the new one I just got was 19 for the rear.

Make sure you get the plates for the lower lnk mounts the eibach bar didn't come with them.

If you push the car too much it will bust the lower mount hole, then you need to get it welded.

I put that eibach on my 12 today works great might go for the front soon, have to do some testing to see if it handles like I want it to.
