Make a ring larger but same thickness Is it possible to make a ring larger, but maintain the same thickness?

I only selected the vertices of the ring, the ring is part of a larger object and I don't want to separate it.

If I simply scale it with S, it becomes thicker as well.
Try scaling in the y axis how much you want, then scale the same in the x axis. (Example with things you type: S,Y 90, S,X 90)
