Two torx in each arch, one bolt hidden under the arch lining on each side. Two bolts under the car to the tray. "Some" (because I can't remember how many) torx along the bottom of the bumper. Two large torx under the grille. Couple of posi drives/torx on the top of the black plastic bit covering the T-bar.
As long as you get the ones behind the liners the rest you can see or find easily. Sides of the bumpers, where they meet the wing, just pop out.
This
guide by Fubar should help give you an idea, even though it's for a 182.
