These pistons aren't like that. The pin is centered in the groove. On a good note though. I flipped the ring around and the grove is such that the ring won't compress if it's on upside down the ends of the ring will not even compress to the pin. I guess I should have tried it the wrong way first!
I think the set up your talking about is on Wiesco pistons. Also the bevel I was talking about is the whole ring on top is beveled, there's no bevel on the ends of the ring. It's actually notched out for the pin.
