If that is the exact kit you bought, I don't think that will work. The front hook on Subarus is hidden behind a small body work flap on the bumper. Remove the flap, and there's a large 16mm(?) socket. Dig through your spare tire tools, and you'll find a D-ring mounted to a large bolt that screws into place on the front.
On the rear, look under the rear bumper for loop bolted to the frame.
