Arguments for solid vs poly?

I went with the Z1 poly diff bushings. The reason: For the rear diff bushing, if you mess up the install and it doesn't seat right, you're in trouble. I knew with the poly bushing that if the install went poorly, I could simply cut it out with a saw-z-all and start over. The poly bushings have worked fine for me ... but I don't launch the car and put undue stress on the diff.

I too have poly differential bushings, but they are whiteline.

I beat the **** out of my car when drifting it and it has held up fine. I did maybe 4-5 events before I added a GKtech diff brace to it. Haven't done anything for the subframe bushings yet though.
