Anyone using solid suspension bushings?

Specifically solid aluminum lca bushings. Thoughts, experiences, how is the life-span of these? I will be driving this car on the street.

I know a couple people that made solid delrin ones, but not alum. Delrin holds up decent, no idea how alum will do with street use

Solid bushings won't work in stock type LCAs; some give is needed to allow twisting. Rod-ends satisfy the twist requirement but are quite noisy. Poly bushings are the usual compromise.

Why is give/ twisting needed?

Mainly because of the roll motion of the axle relative to the body. There is also some side-to-side motion due to the track bar (panhard rod) arc.

So, would not having the motion cause breakage?

I have rod ended solid bushings, but I never notice them making noise, but that is because my car is loud.

I just feel them.

Yes, sooner or later a stock LCA with solid bushings on both ends would break; they would be forced to flex and they are designed to not flex. If you are determined to try the experiment, there is probably little danger because it is not likely they would stay on the car long enough to break. I expect you will soon hate them. BTW, 1.5x sixtys, maybe better, are possible with completely stock f-body rear suspension including stock rubber bushings.
