| I've read a lot over the years about the importance of using real bushings that allow some give since the arm wants to rotate a small amount as it moves up and down. I was curious if most ppl agree or just disregard it? I was focused on the Z1 arms or maybe even Stillen since they both use poly bushings. I can't even find the UAS arms listed anymore, but thought those allowed rotation as well. I do have SPL tension rods. The video I've seen of that rotation is exaggerated a bit since the arm goes from full extension to max compression. I imagine most cars will only experience a few inches of travel at most.
