Got new tires and had alignment done. Initially, left & right front Toe, left camber & Toe were out of spec. Three were brought into spec. Left Rear Camber remained out of spec and became worse.
Initial = -1.27
Final = -1.33

Spec min = -1.25 max = 0.25

Should I be concerned?

I was told by PEPboys that changing others caused this one to be out and there's nothing they could do without some type of suspension (eg spring) replacement. Is this bull?
