Also, I was putting my pads on tonight and as promised before I measured from the center of the hub to the edge of the caliper. For those trying to determine if they will fit your wheels. It measures roughly 6 3/4 inches, maybe a little less (This isn't too precise because I am just feeling for the center of the hub).
Here is a closeup showing the gap on my 18" tsws (with normal pads, not the odd Camaro ss pads with their weights).
