The rear "Springpan" and the rear "Dogleg", together make up the lower wishbone.
The "Springpan is much longer than the "Dogleg"..
Therefore the "Springpan" moves through an arc of much greater radius than the "Dogleg"..
Also the arc centers are in a different plane.
Both are attached to the hub carrier/upright. This arrangement causes the upright to twist..
Toe in/ toe out..when the suspension compresses or expands..
This is induced by body roll when cornering.
One side expands.. the other compresses.. one side toes in.. the other toes out.
The amount of toe in or out is proportional to the degree of suspension compression or expansion induced by body roll.
Therefore resilient bushings are required. Spherical, rubber, poly etc..
If the upright were not allowed to twist.. the suspension would lock up solid. Or the bolts would shear.
Therefore based upon the fact that the suspension does not lock up when Powerflex bushes are fitted.
It is reasonable to assume that the passive rear wheel steering is still operative.
So.. what Mitch says is very true.
And.. why body roll can be a good thing.
The only way to negate or reduce the rear wheel steering would be to modify the car in order to reduce or eliminate body roll.
Gettin' to old for this sh*t
