It's a funny old game. I've certainly had a couple of rear AVO's bottom out and leak, but Rog's assists prevent that.
I also found the non adjustable original Spax on my Plus 4 to be very good,
So far I haven't had any AVO bushes fail, but I did have one rear metal damper mounting fracture, so at the rear especially, the engineering is a bit marginal. Roger has already highlighted the compromised geometry of the rear dampers in terms of twist under compression. To be honest it's a wonder we don't see more rear suspension fails.
