Warning about Professional Parts polyurethane bushings

My experiment with freakishly cheap Professional Parts torque arm mounts has failed.

Here is my original post (still contains a helpful technique for removing the alternator-side OEM mount without removing the alternator bracket): http://www.saabnet.com/tsn/bb/9000/index.html?bID=315609

I changed every drivetrain mount about a week after installing the Pro Parts polyurethane torque arm mounts. In the ensuing two months, significant free play redeveloped during on/off throttle transitions. One nice day I opened the hood, put the car in gear, pushed on the front end and low and behold--the Pro Parts torque arm mounts had basically distorted/worn to a state worse than the worn-out rubber mounts. The failure occurred on the outer part of the split bushings, where they are seated in the race/housing. Basically the material was not strong enough to maintain its shape.

I purchased PowerFlex yellow mounts and installed before my morning commute. Unlike the Pro Parts mounts that required modification, the PowerFlex bushings actually fit properly, which is always a nice thing with automotive parts. The car felt immediately better, and to my surprise the most improved aspect was the handling when lighting up the tires under boost--far less comedic sawing at the wheel required to keep the car going straight. The bright yellow color also increased the under-hood Bananarama factor several orders of magnitude.

I have an entire Professional Parts front end kit that I will not be installing. If a large, fairly lightly-loaded mount fails like that after a few thousand miles, it stands to reason that a swaybar bushing loaded to the hilt with levered crushing forces won't fair any better.
