Every Hyundai I have ever aligned the caster measurements have been lower then what the spec says. Caster will not cause a pull (unless caster split between the right and left is huge). Positive caster is what causes the steering wheel to self center. The only pulling factor is the toe and it would have to be out pretty good. You also need to keep in mind that must roads will have what is called road crown in it. It makes the road look like a hump in the road with the center of the hump in the middle of the road. It is there for rain to drain. That is the number one reason that your vehicle will go to the right due to the slope in the road. You should take your car to a road that is flat, as not all roads are flat level roads and check your alignment there. Post up all your alignment measurements too for me to look at.
Oh one other thing coupe or sedan?
