Cheers for the comments.
Not much new to report really apart from finally getting a camber kit fitted.
Nice wad of shims in there now and were back to regular camber. In ford's wisdom (or lack there of) when I got the car back from the suspension shop their alignment showed the rears with positive toe one side, negative toe the other side - they determined that it would have been fun to keep straight

All good now.
Do feel sorry for the car though - I use it to commute around in peak hour for trips under 5km - really kills the fuel economy and the purpose of buying a V8!
