I talked to SLR on Friday. The shipment with our goods has left Bilstein and is on a boat and can't be tracked precisely.

At this point there is nothing more that SLR can do about it. They were quick to offer a refund if I wanted. They may suck at returning emails and phone messages, but have answered the phone and been very helpful almost every time I've called.

Welcome to the world of aftermarket vendors. These guys are manufacturers, not customer service specialists. It's frustrating, but until these companies get big enough, that's just the way it is.
