lets talk V4 steering head offset..

Tge picture demonstrate the RS set up what the std v4 should of been like … with a ride height adjuster…
 
The RS rocker is available part number 372.1.216.1a, Forsaken Motorsports also makes a knockoff (still has the tie rods though)and I believe Bruce Wayne machined one as well. The ride height adjuster is nominal, easy to make. The RSP shock is also available if you want to spend the money. If you do, PM me and I will send you the info on where to get it. There isn't anything special about RS parts. Solidworks and a CNC mill and you have RS parts. Yes there are dimensional engineering considerations but again, simple, were not talking re-entry vehicle scale complexity here also making your own parts allows for the inclusion of experimental variables that may help your effort.

Ok so looking at it, it looks like the adjustable ride height rod replaces the the fixed tie rods so you are going to need the RS rocker. The bigger issue is that it looks like you are going to have to modify the swingarm as well. It looks like the adjustable ride height rods sits in the center of the swingarm mount where the stock tie rods bolt to the outside. You would need to machine a slot in the swingarm mount to accept the ride height rod

I thought I said all that in post 38
It needs a seingzarm mount centre machining out centrally to take a single swivel bearing a flat rate rocker machined so tge shock and tie rod mounts are the opposite to run with a std TTX tgat has a modified bottom like the rsp… at a reasonable price

My bad, I didn’t read the whole thread. Shock mod, easy. Swingarm mod, easy, ride height adjustor, easy. You would just need the rocker.
 
And, this is the big issue with the eccentric hub. It ..... so much, when it's moved.
So, you adjust the hub, and then adjust shock length to correct the ride height. But then your wheelbase is now different, meaning different weighting of each wheel, so you have to adjust ride height to get the balance back. But, now your geometry is out, so you have to adjust front ride height to compensate. Which takes a bit of trial and error...

I think it would be simpler to redesign the hub.

The RS swingarm uses an oval hub does it still have an eccentric function? This is the F-18, the F-22 is the same so it is not eccentric. Not sure how they accomplish chain tension. 882ACE4B-25BF-406F-AB7A-1E3B10CEE61F.jpeg
