Planning on putting a rear sway bar on a 1990 civic sedan ex. Are the crx si and civic hatchback si rear sway bar a direct fit? also will the 1990-93 integra rear sway bar also be a direct fit?

 

putting an Si rear swaybar in your 4dr is the same issue as putting it in the DX. the holes are there, but the welded nuts are not. so you need a way to fasten it to the frame.

there is a thread in the faq, which also has alternate methods. theres several ways to accomplish it.

the DA rear sway bar is not a direct fit. the geometry of the bar is not identical, and the bracket is completely different. and its overall smaller than the CRX Si rear bar. so no advantage.

 

ok thanks

 

4dr DA rear sway bar is bigger than ef and 2dr

 

marginally and not easily found.

and isnt a perfect fit.
