By fixed I was referring to them balancing left and right rear .. worse than out of spec angles is a misbalance left to right, car was toe in on one wheel toe in on the other. Car is then just a handful, with different stability characteristics in left or right hand turns.
Factory toe settings are still not met and I would not be surprised if the shop did not have them and was shooting in the dark. I would blame this as much on the OP as them, with any sports car (common or as a Miata or as rare as an Evora), I would bring the alignment specs that I expect the shop to produce. Prior to the start of work we agree that they are either factory specs or that owner takes responsibility of the settings, we also agree on what must be absolutes and what can give if camber and caster are mutually exclusive.
As to the OP’s results original is “undrivable; final values while needing another go at it have improved front toe in by have , balanced caster within spec, dreaded rear twitchiness with over compensation of toe in but at least balanced side to side to 0.1 mm from a terrible 1.5 mm delta. This also shows up in trust angle getting back to 0. Good no, drivable yes, Aggressive for track turn in response no.
PS plus (+) toe eqauls Toe-in ..(-) is out
General stettings -
Toe Front: For street, one wants front toe-in, for fast track toe in, auto cross netral (0) to out.
Toe Rear: For street, one needs front toe-in, for fast track toe in to neutral, auto cross 0.
F/R Camber: negative most importantly balanced LH to RH
Castor: minimal and most importantly balanced LH to RH
Trust Angle: 0
