I did end up install it permanently. It's been holding up well and still looks like the day I installed. It screwed into the black undertray without having to drill into my bumper. So far I've done a couple 100+MPH passes with it and also scraped a little on a steep driveway without issue. Lol, sounds like the "cheapie" wing doesn't look so good in fake carbon fiber. But I have one in glass black and will keep it on, still one of the best looking wings I've seen but I am biased.
