rear bumper has a torx screw and a phillips on each side by the rear doors. then 4 nuts on the bumper reinforcement and it'll come right off for you. as for the front bumper, theres just a couple bolts on each side (10mm correct me if i'm wrong) and a screw on either side holding the inner fender well in. then directly on the bottom, there should be a weird rubber push pin thing going right through the bottom of the bumper. theres also a couple push pins on top and then the front bumper will come right out
edit: there are also little metal arms that attach to each corner of the front bumper that have a 12mm(??) nut on them
