I don't think Joe anticipated the interest. He is busy!! Lets see if I can help.
The single picture does not even come close to showing "how it works." Basically it is two LONG lower a-arms pivoting parallel near the center of the car. The two pivots are about as wide as the center double ended 30series size CV, special made by RCV (Maybe 8" or so). The height of the pivots are at the CV center...so the lower arms are actually at axle/half shaft height. The lower arms go out to the upright and pivots horizontally (holding the toe) also thru the CV center. This minimizes or eliminates plunge, and keeps the arms up as high as possible.
The right or "passenger" side arm contains the driving differential (visible in the picture.) The lower Arm also controls braking torque and differential torque on the right side. The inner pivot is maybe 4 feet long to control these forces, and a sway bar helps to equilibrate those forces side-to-side. With the inboard parallel pivots the toe is always inline with the chassis. All these parts are Beefy!
.
The Diff location and pivots start the confusion with a TTB, but different also is the upright has a top single link to control camber like a simple double Arm.
To suspend all of this, Joe did not move too far from what is known good. Each arm has a "common" trailing link with shocks and bypasses at about a 50% ratio. It is firmly mounted to the upright end with a spherical bearing but the forward-frame end is held with a shackle which independently moves as the lower arm stuffs and droops. Pretty unique and probably allowed them to find shock and spring tuning quickly..
A few of us have had time to see some of the videos from KOH and the car definitely seems different from others in acceleration. It accels forward without lifting or diving the front end. All with minimal wheel spin. It just goes. Different from Desert maybe is weight ratio. KOH cars are usually 50/50, and this one weighed in at 49/51.
Several have worked at moving the lower arms up to the half shaft height. And this may be a way around $30k centers with close CV's. Lots of merit in the thought and fabrication here..
