Anyone know what kind of pads these are?
 

A friend gave me a set of lightly used pads for my big reds (964 turbo / 928 GTS), and he didn't know what brand or comound they were. He is sure they are a track / race pad of some sort, probably a Hawk or PFC. I have been looking through pics of Hawk and PFC pads, and none seem to have rivets like these do. Maybe Carbotech?

Thanks!

Possibly Carbotech but CTs usually are color coded w/ paint.
