Idk about others but the "wings" of the anvil were rubbing really bad on the body of the car. Wish I had caught it sooner as it did do some damage after only a couple days :(. The pads didnt do much if anything to prevent it. I had to max out the rubber stoppers for the trunk way up to avoid rubbing. Just something to keep in mind!
Wasn't the spoilers fault. I adjusted the bumpers up as soon as I installed the spoiler . You can tell if the pads are going to rub/rest on the fenders.
