>>>I had an interesting talk with Dennis Quella about all this.   He said 
that he had the shaking brakes syndrome on his own car, and worked hard to 
find the cause.

He said that there was an undocumented change on the steering arms, and 
that some of them were more beefy than the others.   The caliper mounts to the 
back side of the steering arm.   On his car, he had the less-beefy kind; 
once he discovered that, he created a steel gusset and heliarc welded it in the 
weak point.   But at the same time, he switched from solid-mount rotors to 
fully floating rotors.   The problem was then completely cured, but he 
doesn't know what actually cured it.

On an un unreleated not, Scott mentioned that his caliper mounts are made 
of steel instead of aluminum.   I never realized that PPC's were aluminum.   
Although that's nice for lowering weight, I wonder if it wouldn't be a 
better idea to use steel there?
