Body Bushings- Mike's Rubber vs Poly

[Supercharged111]

Also you having replaced only 2 bushings with poly leaving the rest probably worn out only exacerbated the vibration you felt.
Apples and oranges brother

Actually the rest were in really good condition. I had all 6 off and only the fronts were trashed. I think the spray from the front tires lead to the demise of the front cab mounts.

I've never driven my car more than a couple miles with the poly mounts. I kind of wish I had known they made solid aluminum mounts. If I ever change frames or body's in the future I'm going to stick some aluminum mounts in just to see.
