I'm basically putting in a whole new suspension in my 91 camaro. Tubular k frame, a arms, rear lca, panhard, torque arm. i was wwondering where should I be using poly bushing and where should I be using spherical rod ends? thanks. It will be a hot rod driver maybe some drag time.

 

I don't see a problem with poly anywhere but on the rear LCAs. I'd use something like what I did or rod/poly on them. But my car's more of a corner carver. There are better options for the front control arms. The Del A Lum from Global west are better than either if using stock control arms. How much you use rod ends really depends on how much road noise/vibration you want.
