The kit comes with a few things.
3m tape with primer that makes it stick waaaay better.
Front bumper is held on with tape and screws.
The side skirts are held in with screws in the bottom and tape on the top.
The back bumper is taped on, screwed in the wheel well and brackets on the bottom to hold it stiff (lowers the bumper by about 3/4 an inch.
Ones of those pics has my original rims, SES look way better!
