Unless Roush has redesigned the shock, which I highly doubt, there should be no issue. I have never seen Bilsteins sold where it states for lowered cars only. Bilsteins are a high quality shock. I would install them, may take an hour, and drive the car and see how it is. I have some Maximum Motorsports 1" lowering rear springs that I would sell you cheap $50 if you are worried about it.
