hi adam,
yup the front bumper will have to come off. a quick list of everything that needs to be removed to get to wing.
-wheel,
-inner arch liner,
-both headlights for easier access
-bumper (~3bolts on top, 4 underneath)
4-5 bolts for the wing are on the edge under bonnet, 2 bolts behind the side of the bumper, 2 behind the wheel arch liner near the door
hope that helps.
