Front fender trim question

Got some wheels with an aggressive offset and Im rubbing on my front fender. Ive already got a cmc and I hammered down my pinch weld so now I'm left wondering what I could cut without my front bumper flying off. The part that my tire is rubbing is on a mount on the bumper, only way is to trim that off but is that going to make my bumper fly off/ vibrate like crazy on the highway?

 

Anybody trimmed this off without any issues?

 

Someone probably has. Doubt the bumper would go anywhere, but maybe you’ll hear vibration?

Take the screw out and drive around a bit to see if you notice vibration. If no then you can trim.

 

Good idea thanks man
