Ok I've just had a geo done today and the only thing that wasn't in spec at the end was the right front caster.
      left front                right front
camber -1º13'             camber -1º08'
caster 7º41'               
caster7º09' (range 7º17' to 8º17')
toe 0º05'                    toe 0º05'
Is this something to be worried about as it apparently can't be adjusted on my car...
