Yup, worst wear - all the way through the liner - on the front of the front driver side (proper driving on proper roads last weekend though...). Some on the rear driver side and front passenger side. The car seems to sit a few mm lower on the drivers side front and back on a completely level surface without me in it. The driver is 15 stone though, so that must have some impact
My brother suggested that even if the shocks and the rest of the suspension are 'good', as people tend to be more confident into left hand bends this could have an affect on wear rate of the components. Sounds logical, but I have no idea. Like you I can live with it, and will get a new arch liner at some point.
