solid mounts available around, also poly. Not rubber thought.

IF YOU ASK ME... poly... solid will be fine like earliers models but after ride a Dart without isolation and my car ( with RUBBER pices made in Venezuela ), I wouldn't replace the comfort of a rubber piece... POLY as much, but never solid.

thats just my opinion. Of course Caracas streets are a mess.

Rubber pieces also keeps a safer unibody.

( I am one of those who thinks that comfort and performance can be hand in hand, ESPECIALLY on streets even with a HOT street car... I would find the way to fit an A/C on an Hemi car... yes )
