There is “in spec”, and there is in spec. There is normally quite a range in factory specs. Sounds like you need to reduce the amount of toe in, setting it closer to the zero end of the range. Physically impossible to get a good alignment with string. When I do alignments, the machine gives me a very narrow range (1/10th of full factory range) to use, based on the ride height of each corner. Turning a tie rod only one wrench flat will go from too far toed out to too far toed in (only a 4 minute difference), you can’t get that accuracy with string. Plus, I only work on one brand, so I know when to use factory specs, and when to go outside those specs to prevent unusual tire wear, which happens on many models. The new G01 X3 will destroy the outside of the front tires if you set it exactly to factory spec.
Do you have a print out of the last alignment?
