Hey, in the process of doing 5-bolt.
I would like to pick up new or bare used rear control arms in case something goes wrong, but to make install easier mostly.

Looking at Honda and Acura catalogs they show different part numbers for all three chassis, but I noticed some bolts are different lengths and size.
For example the non-adjusting knuckle bolt is 12x75 on Civic, and 14x75 on RSX, that's a different size completely, also the lower bushing it goes into is a different part number between the two.

Which confuses me because I thought everything was the same, meaning I could use all the Civic hardware in the RSX knuckle, or do I need to use all RSX bolts and rear control arms now?

The strut mount is also wider on the RSX.

Have you read the suspension compatibility FAQ?

Most of your answers should lie there.

Where can I find the compatibility list?

FYI, if you DO decide to use RSX trailing arms, the lower strut mount on the trailing arm itself sits about 1/4" lower than the Civic (non-Si). At least, with the 05-06 RSX trailing arms. Thus dropping your rear-end roughly 3/8". Be sure to account for that, should you decide to lower your suspension.

I have them on mine, and yes, I had to (carefully) drill out the front lower bushings on my Civic's rear hub carrier to 14mm and use a 14mm bolt

Sorry my phone was acting up earlier and I couldn't paste the link. There's a lot of helpful info there with links to more.

Thanks.
I compared 01-03 and 04-05 part numbers, of rear trailing arm, and they have different part numbers as well.

I'm going to assume they are compatible though. I didn't see anything in the FAQ regarding rear trailing arms..

I suspect the sway bar brackets are different as well cause I know the RSX end links won't fit our civics but the bar does.

Good to know, my man! Thanks for the help and responses!
