I know the benifit of swaping the original rubber suspension bushings for the harder poly bushings for motosports use, but what about the non suspension poly bushings? I have seen ones for the steering rack, belt tensioner, even exahust hangers.
Does anyone have miscellaneous bushings installed, and what are your thoughts on them?

 

i have engine and trannsmission and all are fine except for the top mount insert behind passenger dash that caused vibration at idle and a/c on.Exaust and belt tensioner i never knew existed.
