I wonder what convinced mazda 2mm seals would be good idea then.

I looked at 2nd gens forever, and have decided someday I will own a vert.

They THOUGHT that they had managed to make seals that would last just as long as 2mm seals with very controlled testing. And get the benefits of the thinner seals (lighter rotational mass and less wear on the rotor housings themselves due to less material rubbing) but they didn't account for carbon build up or flex wear as much as they had thought and consequently the FCs don't run as long on the original engine as the FBs.
