Poly or Rubber?

The polys do transmit more harshness into the ride. My experience was that with the 235/60-15s on the Demon 318 on rubber, I could feel the front end twitch through the steering just a bit. The /6 Custom on rubber bushings and 205/60-15s do not exhibit this. When I put the polys in the Demon, the twitch disappeared. It now steers better without and twitchyness.

yes, some tires may dampen some of the harshness. That is a good point.

I had the same tire/rim combination for the whole time and mine was based on observing just how the two different bushings affected the ride. The bumps were harder with the poly's and they did not last as long as the stock rubber style. I have literally gotten flat tires and bent rims from the potholes in Detroit when I was living there, even with other cars. Their roads suck!

For a daily driver/cruiser, I would go with stock rubber style.

I would only use poly if you plan on road/ralley racing and need the stiffer handling.
