Yes, it is true that these caps are quite light and cannot withstand excessive force. Soooooo DO NOT use excessive force. Make sure you use them in your garage or somewhere warm. Make the settings first, try them out, and then adjust them again. Patience will pay off. ONE of these OEM's is double the price of this whole set of 4. When you finally install them, use your favorite lube like WD-40, preferably one that won't damage the plastic, and USE it on the wheel and lugs. wheel cover. Take your time and be happy. Great product for the price. Only $30 versus $300 at the dealer. Buy coffee with what you saved!
