I wouldn't have thought suspension camber etc would case the saw tooth issue with wear, would definitely cause inside wear (as happened on my old M3) but altering this would, I assume, be detrimental to handling as already mentioned. I can handle the inside wear it is the saw toothing that is the issue. I also assummed it was worn shocks on car, as strangely I run exactly the same size tyres as Neimad, have only run OE dunlops (which have all had the same issue) and I also have 85k on the clock but on a 55 plate (05 car).
However, the handling seems good, the shocks firm and no rebound problems (doesn't mean they are not shot) maybe it is the pesky dunlops, but have a realtively new set on so not keen on changing till they wear out (get good milage on them, in spite of saw toothing on 3rd set in 85k miles).
Maybe I should try vreds and also get a proper suspension check, (not Kwik fit who will obviously just sell me new dampers) or just buy some new rear dampers, they are not that dear £42 per shock for gas billies from Euro car Parts, prob as cheap as getting them tested, and should be v easy to fit.
