Polyurethane or Rubber

I am running full Poly bushings from PST front and rear except on shocks. They are in a B-Body for the past 10 years. Tubular UCA's, Heavy Hellwig sway bars and frame connectors. Handles awesome. Zero issues. Set up for handling so it is a little stiff but also have low profile 18's all around.

Edit: Oh yeah. I am in NY with possibly the crappiest roads in the country.
