This reminds me of Monster JAM trucks. They click a toggle switch left or right for the rear steer. Very cool.
So if you don't need the rear steer you don't touch the trim switch and the rear wheels stay straight?

This sounds like fun! Any durability issues with the rear? Does the rear stay straight and centered when you're not using it?That's right, it just stays straight until I click the switch one way or the other.

If you add a little caster you can get allot of steering out of those axles.
Aloha Honeyman here this build is equally amazing!!! the build im doing is also 4WS as is my next TRX4 project I might need some tips on the links but I think I understand the mechanics of it!!! its going to be a little harder on the trx4 but for the gspeed build I got all the parts to put front and Rear servos either on axle or on rail so ill be in touch about that!!!
my email is omhoney108@gmail.com I can send you pics on here of my build so I don't mess your thread with a bunch of parts and build pictures... BUZZZZZ.....
LOVE this build. All of the time you have spent testing, tuning and tweaking is evident in the pics, these posts and the awesome finishes at comps. This rig seems to defy form follows function, It seems to have both in equal measures. Awesome job!
Thanks! Regarding axle or chassis mounted servos, it depends on what you're going for. If scale competition with scale points (SORRCA) are in the plan, I'd definitely go chassis mounted up front as its worth 5 points. For the rear, going chassis mounted only gets 2 points and IMHO its not worth doing. I've played around with chassis mounted in the rear and it can act kinda funky, I prefer axle mounted for the rear axle for sure. Just keep in mind, you can't do a four link with chassis mounted servo (severe bumpsteer). You typically would do a three link with chassis mounted, four link for axle mounted.
You could make a thread and get input there as well, but message me if you want.
I'm using KNK body post mounts for the front, and a single mount at the rear of the cab that I made. Originally I designed and printed sliders that the cab could attach to with screws but I didn't like having to deal with the screws in order to remove the cab. I think gspeed might have some body mount sliders available for certain bodies now.
