You need some compliance in the 3rd link, otherwise you'll greatly hurt rear grip.
Are you talking about hard, sudden throttle application here, where the compliance would have to be in the tensile direction of the UCA to take some of the shock out of that throttle application?

Or is there some other limit involved?

I haven't actually needed to do anything about the UCA in my car yet. But its OE bushings are getting old so I would like to know what the objections might be to various aftermarket options involving sphericals. I'm not interested in poly/poly or similar.

In for that answer as well.

In a turn, I think that heim joint(s) in the third link make the axle side move in more of an arc since the arm is relatively short...axle tube would also roll forward, change pinion angle, and 'upset' the rear more than two rubber bushings would. It would be a lot of extra movement through even one bump/rebound cycle.
