These CF lips were not installed correctly, I would urge people to read the factory DIY pdf (
http://www.e90post.com/forums/showthread.php?t=1910). Those 3m onesided stickers are to be placed on your car to protect your paint from the adhesive that needs to be used. Its the 3m stickers on the car, then the betalink adhesive then the cf lip. Its glued in place and taped on till it dries in 6 hours. Chris
