The problem is that poly ain't the end all be all of fixes. It is hard, but it's strength is debatable.

I had a poly bushing fail a couple of years ago. It was on the rear spring perch and when it went, the spring went with it. I have talked to Jack @ McJacks Corvettes and he has seen a number of failed poly bushings over the years.

The other issue is the way the rear suspension is laid out. The lower control arm is under tension, and that adds insult to injury. It also causes the rear to potentially bind when using poly, It was this reason I did the Banski kit. I know, it will fail an NCRS test but I don't care!

The only known fix is to find NOS suspension arms. The rubber parts are poured in, as I said above. They are not inserted.

The front is better, but I still donno if I trust poly on the control arms, at least if they fail, the entire suspension won't fall on the ground.
