Wheels 16" inner diameter - HELP.
 

Hi all:). Buy clamps to my car with a Porsche 986 (as in the picture). Nowhere on the internet I can not find, so can you help me?
I know that at the terminal enters rim 16 ", needs from someone on this board about the drum rim(16") diameter wheels. How much is a centimeter, if anyone can measure was'd appreciate it.
