They have been used in a few engine builds over here in the UK without any problems.

They appear to be the same material as the new RX-8 seals. This is going on information sourced from Aus.

the rx-8 seals are much shorter (4mm?) and I am not sure if they can be used in a regular 13B.

Sorry I sort of posted my last post without clearing something up.

The RX-8 seals cannot be used in a 13B engine, but Mazda have released new 2 piece 2mm seals that appear to be made of the same material as those from the RX-8's engine.

same part numbers as the old seals apparently. The new seals superseed the old ones according to another recent thread in which Mazdatrix posted (should be about 1 page down from this thread IIRC

size will be roughly the same as they are a direct replacement. I would guess they have changed the material for the better. (and maybee a few subtle design improvements)

I wonder if they have a 3mm derivative of that. I'll be rebuilding my engine with previously-cut 3mm rotors...

Good. I wasn't sure if they still made the GSL-SE seals or not.
