Poly or Rubber?

Getting ready to rebuild the suspension in my 70 Monte Carlo. Looking for suggestions on using Poly versus stock Rubber. Pro's and con's etc. TIA

Poly gives a more firm positive feel to the suspension. Some say they are too harsh for a street car. Poly bushing if not carbon impregnated will squeak and drive you crazy.

Rubber bushings more closely match the original feel of the suspension.

The choice is yours.

Look into high durometer rubber bushings like the Moog Problem Solver line. You will get firmer bushings without the binding of poly. Personally I would skip poly all together unless you are willing to assemble, check clearances, disassemble, modify clearances, drill, tap, and install grease zerks, and reassemble. You also might want to look into Delrin bushings like Del-A-Lum from Global West. They are very hard but low friction.
