I am beginning construction of a 1990 Firebird in IHRA Crate Motor Stock. Looking at the bolt on suspension parts, I see that most torque arms use a "energy poly bushing" at the torque arm front. My question, since this is a dedicated drag race combination, why the poly bushing? Why not some type of rod end or solid bushing? Or, is the poly so hard deflection is not an issue? I have the same question about the lower control arms, why not solid bushings?

Thanks
