So Rear Disk Brakes you say....

WELL... I did some homework while working on our HHR with the short amount of time we had on it. Also being in Southern California I was in contact with the guys at the GM Design Center and spoke with a few of them at the SEMA Show. And the white HHR Concept they did had rear disk brakes. Some close inspection revealed some interesting options for stock HHR guys. I just need to work out some part numbers and see if its possible to switch over.

Let you know as soon as I do.
