Then again the hotchkis is a pretty massive bar. If spec on the net are correct I think the eibachs would be a interesting set to use since between the adjustment ranges it’s the only set I’ve seen that can go either way as a stiffer front bar vs rear (in ratio) or a stiffer rear vs front (in ratio). So theoretically they should have the widest range of tune ability.. I was pretty surprised to see the stillen even at the stiffest front setting only being marginally stiffer than the softest rear.

yeah, I think what I'm going to do first is move the end link to the outer hole (softest setting) on the rear sway. You're saying just unlink one side and basically leave the endlink hanging there to test this out? any potential issues I can run into while driving it this way for a bit?

I ran into some really weird handling issues with my car when I went to higher rate springs. The car would dart around on bumps so badly that a passenger could feel it. My issue came down to not enough down travel meaning that one or more wheels was constantly struggling to make contact with the ground. What helped me was adding a set of helper springs to the car. This gave me way more down travel and made the car handle bumps a lot better.
I also don't run a rear bar because I found it much easier to get the power down without one. I just increased my spring rates to get the right balance or rotation for my needs.
Here is a link to my short write up from by build thread:
Rear helper springs

Yeah, the adventure I've been on the past few months trying to get this right has taught me about all the factors that come into play with suspension.
the second coilover kit I put on had custom swift springs at 12k in the front and 7k in the rear (true rear, not divorced spring). This was BRUTAL to drive and I immediately threw on 10k/5k swifts and noticed a huge difference. But I assumed the custom valved dampers for the 12k/7k original springs on this kit were causing it to still be too stiff for daily street driving.
That's why I went with a completely new divorced spring kit, using default spring rates of 10k front and 8k rear. As I'm sure you know, the spring rate is basically double for divorced spring vs true rear coilover spring due to the wheel rate.
This was also noticeably better, but I'm still feeling what I think you described as "darting" (car slightly being thrown left or right I think?) when hitting bumps with one side of the car only.
The other thing too is that I have yet to get my alignment done, because I wanted to finalize my configuration before spending the 100 bucks and avoid having to do it again if I wanted to change something. I know this will affect handling, but I didn't think it would be enough to cause my issue, right?
As for ride height, I'm not slammed, and I'm not at stock height. I'd say right now I'm noticing this at maybe 1.5 inches lower than stock, so nothing extreme but was planning to fine tune the height adjustment to maybe a half inch lower than it is now, just waiting for springs to settle a bit first.
I'm not really sure what down travel is. I'm on the default dampers that come with the BR series coilovers from BC and I have them set to the softest of the 30 available settings.
I appreciate the responses, guys, thank you!
