I spoke with Bilstein the other day, and they do not have shocks for the 300c in development as of yet. In fact, I was told that they were so far behind on new product development that an ETA for aftermarket shocks couldn't be ventured. He did say to call back around June for an update. I am only about 10 miles from their SoCal development facility, and would be willing for them to use my C if it would expidite. I'll keep pushing!!!
