This is the base setup i'm using with the already mentioned changes + 22mm/28mm strokes
The car is extremely darty on the first steering input. Too nervous and reactive to steering. Will make a vid asap.
just FYI there is a CAL3.1 thread here:

Team Yokomo YZ2 CAL3.1 / DTM3.1

Some thoughts based on what you have stated for setup, issues seen, leveraging my own thoughts and what I use a lot for info here:

https://site.petitrc.com/setup/xray/...2_SetupHelper/

In general seems that setup would have a lot of rotation I would think, relative to the surface conditions you are running on. The Yokomo springs also stand out to me relative to the measured rates being very soft in comparison to AE V2 springs. Need to see the surface but when playing with no sway bars if traction was up, it definitely made the car feel unsettled for how I drive. I also for the cal3.1 specifically haven't liked the more narrow arm position versus what is stock setup from the manual.

Looking forward to seeing the vid. If you can post up what are standard tires used for your surface that would be great too.

Is there any dirt/dust cover ever made for the transmission of the YZ2 DTM2 buggy? Planning to run this buggy on an outdoor dirt track, so will need the dust cover to protect the spur/pinion from being chewed up by the dirt.
Thanks in advance for any info shared.

Unfortunately can't think of anything. You may be able o rig up something through with any of the other covers at least for say the front and all, maybe one from RPM then just cut to fit?

I guess the only feasible option is to adapt the YZ2 DT's 3 gear standup gearbox with gear cover.

There are some posts up on facebook of people doing that to the current cars from what I recall, someone even got pretty inventive and made a rear motor version.
