Hmm....the box says V4 for version 4 I imagine. The guy did say they added copper at 4% but WHOA....there is alot of copper specs on the surface of the pad. The V3(I bought them last aug) were just gray but these are covered with copper colored dots. My only fear is that they are going to be much harder on the rotors. I'm already going to have to grind down my NEW nissan rotors with 15K....which have warped slightly. I WILL scan the pads later tonight to show you. Where/who can host a couple pics?

If I link it to geocites it will just give X's.
