The crests, or emblems have fallen of the centercaps.............These are Porsche OEM emblems, not after market stuff. You cant just buy the emblem, so you have to buy a whole centercap at 54 bucks to use the emblem. You can only buy these centercaps in silver and my wheels/centercaps are black so I take the emblem off the silver cap with a hairdryer and reglue it on my black cap........I don't think they are getting stolen because the car is garaged and I always check the wheels when I get in/out of the car. One time the emblem fell off right into my hand when I was washing the wheels.
