Well pulled apart the rear iron today (and did a few other things), and I found this:

It's about a half inch gap on the lower portion of the iron where the seal failed. Besides that no damage from what I can see. I think all the seals on my rotors are good, but for the most part I'm still attempting to see if the backing of the inner oring is supposed to be like that or not. I thought it was supposed to have rear support all the way around. It doesn't look like a metal failure but like it's been either caste that way or removed by a dremel. There's no damage to the Oring surface, but that concerns me.
And here's a random picture (didn't take any of the car), but it's getting closer and closer to POR15 time. Still got to do the marine clean and metal prep, then tape it up and start painting.
