I've seen these and considered them myself, I particulaly like the encentric rose mounts on the inner linkage, this could make easy ajustment of the camber, but but I fail to see how to lock the encentric joint in place. The outer bushes are very firm nylon type, same material as the ARB blocks and other mounts they supply. I think the nylon outers may me a little aggresive for road use, but if you've got a strong chassie set-up I'm sure it'll cope.
