I ordered my Roush springs on a Monday morning, and got them Tuesday evening, so don't be surprised if they show up faster than ya think!
I got at least a 1.25 drop out of mine, but I think the rear is lower than the front after it settled.
I'm put them on with Koni's and love the ride, not to harsh at all. But I'm going to change them out with some H&R's next year, just to keep my exhaust from scraping speedbumps.
But for the $$, you cannot beat them!
