The Bilstein Touring's aren't designed for lowering springs. If you do put them on the car, they won't last as long. You'll need to pick up a set of OEM sport springs to lower the ride height. But honestly I would wait a few days for them to settle in and then see. I have seen a few threads regarding this topic, but that won't hold me back from buying a set. I found all 4 online for $320.
I wouldn't mind seeing a picture of the car with them installed.
