The toyota ones are aluminum with rubber for each of the pieces. I've seen a couple BMW ones that were full rubber. As far as I know, Febests are an OEM parts manufacturer and these look exactly like my OEM toyota ones.

Besides that, I only know of Polyurethane ones, which I thought would be better because I've used energy suspension components and I felt they would be the same.
