From your numbers the split in the caster looks to be your pull problem.
Chris is an old circle track racer and he says that they use to run the caster split like that. He would run more positive caster in the right front than in the left and it would cause the car to pull to the left which made the car easier to turn on a circle track .
See if you can get them to equalize the caster in each side and that should fix your problem. They need to get that thrust angle to 0.00.
If you want to make the car feel more responsive run 0 toe in the front and a 1/16 toed in the rear end.
Just my humble opinion
