Just go through my list and you should be set
I love this kit, but it makes it difficult to get the car under a lift without driving over some spacers. Those who didn't do it correctly smashed the side blades. My car has seen some serious speed bumps approximately 4" high. It will crush the side blades no matter how slow or the angle of approach is. The next time I replace the blades I will look for something lower profile.
I love the front lip, but it is almost destroyed from encountering some nasty roads and bumps. The replacement will be a replica of some sort. If it gets destroyed, it won't hurt me as much financially lol.
