For the person who posted this thread, I would check around on the internet and contact companies such as Tokico, KYB, Gabriel (yes, Gabriel), and also contact T.P.I.S., among others (they make a revalved shock that I have on my car and I like it a great deal---it's sold through MidAmerica and Corvette Central, I believe---solid flat ride [not floaty or harsh] at a great price). Unless Bilstein returns your call very soon simply don't waste your time dealing with them anymore. One of the great things about the automotive aftermarket today is that new providers of goods and services are comming onto the market, and finding out about them is easier than ever. If you are a bit of a gambler on a new product and don't mind having to explain your decisions to go against the "established products" when dealing with others, you can often make yourself a lot happier by getting a product YOU like at a reasonable price. What's really great is that often you pioneer a new product, others try it, and find they prefer it, too. It's that way with tires, for example, and I have watched as Kumho is starting to make real inroads into the high performance market in this country after the initial snickering about the name and the fact that they were Korean.
