According to the Detroit Wheel site, the offset on the Edge wheels is 52.5 mm and the hub bore is 63.4 mm. The stock wheels on your STA have an offset of 35 mm (44 mm on non adrenalins) with a hub bore of 71 mm. The hub on the edge wheels would have to be machined out, and you might have clearance problems (the difference in offset would tuck the wheels further under the fenders).
