My bumper on the drivers side was similar to yours when I rolled the car off the lot and till this day it bugs me like crazy. This past weekend I removed the bumper to upgrade my intercooler and now the passenger side is just as bad. I double checked all my clips were intact and if things were seated properly and they look like they are, yet I have these huge gaps.
I’m considering taking off the bumper one last time just to be sure. Maybe even buying new bumper clips all around, by the fender area and under the headlights so they’re all fresh and ruling out the possibly of them being worn out. The tabs on the actual bumper itself might’ve also gotten worn out too.. But still.. it’s really annoying, hopefully I find a solution. I’ll keep you updated.
