I know what you mean. On my trucks, after an alignment where they left mine off center, I got down under it and lengthened one tie rod and shortened the other. If the wheel is off to the left, lengthen the left one. (Tie rods to the rear of the control arm) Yourself, with a car and rack and pinion steering, you’re kind of stuck with what you have unless you explain it to the tech. It takes some people years to get a satisfied customer. A straight wheel on the rack usually helps the guy get it straight.
