Zero Clearance Side Seals

[cewrx7r1]

Those special coner seals should seal better, but where can you buy them?
If you had a good machine shop, maybe you could make them yourself.
The question is, where they not cost effective for Mazda, or only used in rcae engines?

Yes Chuck, I am not sure why Mazda hasn't used them for production. Possibly the extra machining and fitting.

I also wonder if the reason could be that the normal blow-by of the side seals might help to float the rotor between the housings.

As for who makes them, I make them myself with a special diamond cutting tool. I can cut a set for you.
