We have replaced every bushing on my friends 72 camaro with all poly and the car went from having a floating feeling to have a real tight solid feel. The car feels very solid when you make a corner and a considerable amount less of body roll. Plus the poly can take a bit more beating into where they need to go.
I have replaced some of my bushings with poly and noticed that what i have replaced seems to work more like its supposed to rather then just squish the bushing out of whack. Once you start replacing them you will see what i am talking about the bushings will mostly just be trashed and you will be surpised that they were working @ all on some things.
POLY all the way for me except body bushings, i still want the vehicle to have a nice ride in the cab (less road feel) but i want the suspension to work like its supposed to.
