Refresh my memory/confirm that I'm correct:

There are no geometry differences between the 89-91 and 92-95 Civics in terms of the rear lower control arms, correct? I recall from 96-00 there was a slight difference and IIRC the bushing was a different size (where the shock mount was).

But, I'm mainly concerned about 89-95 differences. Aside from ones with the swaybar/ABS provisions, all should be the same, yes?

Reason being is that it appears the 89-91 Civic Si Rear LCAs are no longer available from the Honda parts department. However, I can still buy new OEM 95 Civic Ex 4-door control arms that have the swaybar mounts on them.

 

I think you are right. For example, Function7 sells the same RCA for EF and EG: F7EGLCA-3 - Honda Civic/Acura Integra Ultralight Lower Control Arms | Function7 Engineering

From EG to EK the motion ratio increases from ~0.75 to ~0.88 and the shock bushing width decreases from 50 to 40 mm. Also, they're stamped steel.

 

same

EF/DC/EG same. geometry wise at least.

bushings are a bit different. but if theres holes for ABS, or swaybar, that makes it a different p/n anyway.

 

Correct. The DC Integra bushings are a larger diameter than the Civic/Del Sol ones, but the geometry is the same and the arms themselves are otherwise interchangeable between all. I can't confirm either way for DA Integra stuff, that configuration is kind of the wild card for this chassis style.

 

DA rear lower control arms are shorter then 88-00 Civic arms.

Edit: It may actually be the toe arms are different.

 

no.

 

The DA RLCAs are the same overall length as DC/EG/EF, I would consider the EK as the oddball out of thecommon chassis we're used to. I believe the DC and DA toe arms are slightly didifferent lengths but the adjustable aftermarket toe arms should work with either chassis.

^ beat me to it. I was going to mention the shock mount position difference but couldn't remember if the DA was located more inboard or outboard in relation to the others. People use the DC/EG arms on DAs all the time though because DAs receive virtually no aftermarket support. A lot of times the arms are even marketed as 90-01 fitment.

 

Thanks. I searched but did not find that thread. So if I'm replacing 89-91 Rear LCA's then I should be able to use any 94-01 Integra (non-R) or 92-95 Civic (with provisions for a swaybar).

I just did not want to upset the OE geometry by using a different LCA, which I didn't think I would.
