Hi Guy, will a 1999 Integra rear swar bar fit on a 1999 civic SI?
Plus does anyone no the dia of this bar?
I no there is a link somewhere that shows all the sway bars but i can`t find it
Any help would be appreciated.

 

Any 94+ rear sway will work on your civic, but you have to mess around with end link adaptors to make it fit properly. It is only a 14mm bar.

The 99-00 Civic Si uses the same size bar, but has the advantage of using regular rear Si rear end links, no mods needed

Most people opt for an oversize bar like an ITR with is a 22mm, it makes a big difference, but it is in your best interest to get a subframe brace also to avoid tear out issues

 

Yes it will.

EDIT- Deetz beat me to it.

 

Thanks guys, I was hoping it was thicker like you said.
Guess I will have to keep looking. Thanks

 

With the si's front bar at 26mm, the 22mm rear could be just what it needs.

Good luck.
