Rear Urethane Bushings?

[tmontague]

it's your typical "H" torsion beam type axle. Only points of connection to the frame is the 2 front bushing points and then in the rad of the torsion beam where the rear shocks (and springs) attach to.

The shocks/ spring control the rate of movement of the torsion beam but they pivot on the bushings. You are correct about soft rubber ones would lead to more "wiggle" of the whole torsion beam assembly on cornering over bumps (which I have experiences on on curvy on ramps)

What I am not clear about is - does the rotation of the torsion beams depend upon the flexion of the bushing, or does it rotate on the bolts and inner metal bushing sleeve?

If it's option number 2 then a stiffer bushing shouldn't affect the normal movement of the torsion beam, but it would correct the incorrect side to side movement.

If it's option number one then the stiffer bushing would stiffen the rear end in its normal movement, however I couldn't imagine the bushing works like this because it would put a ton of force and torque on the oem bushing and prematurely tear it
