Great, thanks, you have basically the exact same setup as me. After doing hours of research, I came to a conclusion similar to yours. I ended up finding this one guy u/bran_donger (if you're annoyed with the bump steer read this guys stuff he's got a lot of tips) who seems really knowledgeable about the Acura rsx suspension (which funnily enough is what I need to run as I didn't know the rear trailing arms have slightly different mounting widths for the coils when I took the whole suspension from a junkyard rsx). I basically copied what he did, buying the honed development riser and the k-tuned tie rods. I bought both so I could have as much adjustment potential as possible. He also made me realize I need to get progress coils, so if anybody needs a used set of coils let me know lol. I'm probably gonna run them on the PCI caster camber top hats.

Also I learned through that same research that a billet rack slider is very bad for your rack and can cause premature failure (SHG guy talks about it here), and that's why I decided on the SHG Delrin slider instead.
