haha! I am experiencing this for the first time. Test fit my blitz bumper sunday, which is lower than the plastics, and had the bolts out. It made the horrible scraping noise. When I got home and put stock bumper on, saw I lost most of the clips. But I thought I had enough still for it to hold. Was in a hurry today coming home from work, hit 110 and bam off they came, or I should say they folded under the car. I completely removed them tonight, I'll fix'em up tomorrow. What a pain in the ass!!
