Basically, yes. The Hudy balance pins work well for determining if your car has a serious imbalance, but they won't tell that one side if 5-10g heavier than the other.
As long as things balance out relatively evenly, just drive the car. If you are super meticulous and OCD, you are going to need a 4 scale setup to cornerweight the car.
