I'm Working on a Custom RUCA w/ my Alignment Specialist/TECH @ my Dealership.
Basically taking the No Name RUCA's I have on my car now (
which are Perfectly fine BTW) and making the Adjustment as easy as the Camber adjustment on the Front (coilovers).
Making the inside Threaded portion SMOOTH then,the HEIM Joint (threaded) basically allowing adjustment by loosining the Jamb Nuts and pushing or pulling the wheel instead of Spinning w/ a wrench (
in a VERY TIGHT Place) or even removing the RUCA sometimes.
Will prob try to Run them on my Project I'm working on now.
Heres a basic MS paint rundown:

All of the weight is not centered on this one Point (per my Tech),making it a rather simple design - so long as the Heim Joints and Jamb Nuts are Good.
