Some time in the life of my car before I owned it somebody had used the bottom part of the radiator support to pull the car. Maybe a tow truck driver or somebody pulling the car out of being stuck. Anyway, I got it bent back into the right position basically. It's not perfect but good enough. In the repair process I had removed the plastic front spoiler that mounts under the bumper. Since I had installed lowering springs, this plastic spoiler is the only thing that scrapes sometimes. I can live with it scraping now and then if there is a significantly useful reason for it being there. On the other hand, I could omit it. What do I loose by omitting it? Too much air under the car at higher speeds? Anything else? Would you live with it scraping now and then or take it off?
