I just got my order from Mazda Motorsports recently and the stock 3-piece 2mm apex seals that I ordered were substituted by 2-piece 2mm seals. I e-mail them about this and they said that they have changed to 2-piece. I was unaware that Mazda even made 2-piece 2mm apex seals. Does anyone else know anything about these?

I just checked the Mazdatrix website and they have 2-piece 2mm seals as well and no longer carry 3-piece seals.

They are the renesis-style seals, sized for pre-renesis 13B applications. Theres more info here.
