I have some REALLY GOOD NEWS. I was finally able to get through to Stephan in Germany. He still has the Crossfire rear diffusers available but is currently sold out. He is making more and is planning to have 20 sets available in about two weeks (6 of those are pre-orders and I am buying 3 sets so there will be 11 sets from this upcoming batch available). Stephan will be getting me the current pricing shipped to the USA. I will post back here as soon as I know and will also post his contact information so you can place an order directly with him.
