It happened also to me after removing different bolts. They were so soft that the head was deformed. I had to replace them with new ones. In fact the service manual suggests many times to replace the bolds. Does this mean that this car is cheap? No! Think about if all these bolts, studs and other parts of the car were made from high strength steel. Think about how much more the car would weight. Do you know the weight of a basic Porsche Cayman?
