They are 1 peice, 1 spring seals with no markings or anything on them. Some of the packages had RB written on it, the rest mazda, and the seals have nothing.

Thanks!

The 11015 written on the springs leads me to believe I have a set of 2 MM Carbon seals from mazdatrix. Do many people use these seals? I dont think I will use them in my rebuild.

Well, my guess is that RB = Racing Beat. It's a big Rotary Performance shop. I also agree that they are Carbon seals from Mazdatrix. I would highly suggest NOT using them in your rebuild as Carbon seals are only "effective" at very high rpms because they are light and do not chatter like your typical steel apex seal. By high rpms, I'm talking about continuous 8000+ rpms that is only seen in Peripheral ported engines, etc in racing. Anything lower than that and they do not seal well at all. I suggest returning them to the company that makes them, or selling them.
