Another part of the equation is the relative nose up/down/level attitude of the final assembly. A nose down reduces runtime caster while a nose up increases the runtime caster.
Seems this is not so. The Radius Arms are bolted solid to the Axles. The Axles have the Steering Knuckles at their ends. Caster is set at the Knuckles. Raising the front ride height, raises the rear ends of the Radius Arms. This tips the upper knuckle Forward, just like lowering the ride height of a different suspension design (like double wishbone). Seems raising the front end tips the knuckles and that Caster Angle forward, toward Less.
