Haha yeah, I've definitely scraped the bottom of mine a couple of times and my car's not even lowered, but the looks are killer. When I first installed it with the 6 or so screws that were provided, I saw that there were tiny little gaps between the bumper and lip where the plastic sort of wrinkled from the pressure between the screws. So... I secured it with about 40 extra screws and bolts all the way across and now the gaps are gone. That thing's not going anywhere. I think I might leave the lip on during the winter too. I was also tempted to run a line of clear or black caulk (or something similar) between the bottom of the car bumper and the top of the lip just to seal everything up completely, but that might not look so good because of the glossy paint being next to the flat finish of the lip and it would make things difficult if I ever do decide to take the lip off.
