Installed on the car and "0" driving mile on it.  rubber still very soft and in great working condition 

UUC Red urethane bolt-through transmission mount bushings are the strongest choice. A single bolt through the entire piece eliminates any possibility of bushing material failure even under the most abusive conditions. Offers effectively the same drivetrain motion control as a solid delrin or aluminum mount, but with some vibration isolation to reduce vibratory stress on mechanical components. Cabin vibration significantly lower than delrin/aluminum solid mounts, but still noticeable.
