Got a call from Joe today @ Tein. I submitted an application for them to use my Magnum to measure for some lowering springs. They wanted to use my car but I can't get down there during the week. Your car must be somewhat stock, i.e. no subs or any additional weight. He didn't care about the intake or removed resonators. You must also be in so Cal. If you are interested submit an application at http://tein.com/test_vehicle/index.html.
