Brazilian Mopar

Andrev8, take some time and look at previous threads with this topic. A lot of guys have been there and done that and opinions vary. The poly bushings will definitely stiffen the suspension over rubber. There is less deflection of components with poly versus rubber. Most of the road impacts are actually taken up by the torsion bars. Going with bigger diameter bars will improve handling, but you will definitely "feel the road." Some members have used poly, but used rubber on the LCAs to reduce some of the shocks that travel through the components.
