I'm not sure if my information is bogus or not, but I'm told that the thicker ring will seal a little better due to more contact area on the wall, but is heavier and will produce less seal at high rpm's because the ring is too heavy to stay on the ring land, having a tendency to flutter. I'm told that the thinner ring will not seal quite as well at lower rpm's, but will hold its position in the land a little better and have less tendency to flutter at high rpm's due to the lighter weight.

I have no scientific data to back this up, so make your own choices based on what seems like it would work better for you. Most of the stuff I have built was street driven and I used the thicker rings.
