im not piecemealing the information because im trying to hold anything back. its because you keep the discussion going in your confusion and inability to see past the extra stiffness of poly over rubber. its a totally different design. it changes how the suspension works. and i believe in a bad way.
the silver bullet is as ive said. the ES bushings do not allow the control arms to move the way that they were designed. thats not a good thing. youre trying to argue, i think, that its actually a good thing. its not. it is what it is, and its trying to make it what it isnt.
take a look again at the link i showed you. look at how the rear lower control arm does angle forward, as well as rotate up and down. the arm is naturally going to want to be in that position and ES bushings are not allowing it. in the end, the bushing will bind the suspension, cause more friction, heat up and deform causing more slop.
but all this discussion about dynamic caster is a red herring. its not pertinent to why you shouldnt run ES poly bushings. its a totally different subject.
switching out the front radius rod bushings for the sake of reducing change in caster while braking is a good thing. ive switched them out for poly too, didnt notice a difference over stock rubber. ive heard many positive responses however about switching them out for spherical bearings. look at opmautosport or sbms. same effect as your changing the whole crossmember.
continuing onto a totally different subject, but since you mentioned it, the only reason you get stiffer springs (in racing) is to limit the dynamic changes in caster, toe, and camber by limiting the suspension's movement. like i said, totally different subject.
