Hey, guys/gals, if you have an x line or non m sport f15 and want to replace the diaper on the rear bumper, I have a rear diffuser(only the center part in the picture) with under 500 miles on it $150 shipped, few minutes to install. I also have both aluminum from and rear panels from the x line for anyone interested and the bottom half of the rear bumper, front one as well. Thank you.
