So... I got a message from Summit on my phone. "The wheels you ordered have been discontinued. Unfortunately they don't offer a +0mm offset, but they do offer a +30mm offset which should push the wheel out about 1.1 inch."

I called them back and told them I didn't order a +0mm offset wheel. They checked my order and basically said, "Crap, we must have called the wrong person as we thought you did." Hopefully this means that the wheel is available and it should be shipped soon. I'm getting tired of every wheel I order being discontinued.
