David,
Did not know that they were new. If you just installed these lug nuts and they are brand new, then get a real socket wrench and breaker bar and take every one of them off and put the old ones back on your wheels before more break and you lose a wheel!
I have used Porsche lug nuts for over 20 years now and not had a single one do this. I personally would worry if these were all defective and would return them to where you purchased them.
Wonder if these are aftermarket and not up to normal strength or if they were heat treated correctly? Something is not right here... Did you buy them from a dealer or reputatable parts house?
Joe
