Phil,
Mine were so tight that I took the car back to the dealer who also had problems un doing them. The near side rear was done up to 380lbs on their wrench. I have now fitted spinners which are far better as they look the part and, with the aid of a good Thor hammer, you can undo them with far less chance of damage to the wings.
