Not sure if anyone has already done this, but it is my way of avoiding drilling through the bumper.

I used two 1.25" 1/4 Phillips head bolts, 2 Locking nuts, 2 big flat washers, and 2 rubber adhesive tabs.

I removed the front radiator plastic cover and simply reach my hand down to tighten the bolts. I then put the rubber tabs on the back of the plate so it wouldn't cause any damage to the paint on the airdam.


I don't think it looks too bad and it sure does beat putting holes in the bumper. I don't think it should block any major airflow either. Pardon the bumper picture, it's been raining really bad.

 

haha not bad, problem for me is my car is low enough as is

i just use L brackets and screw it to the bottom of front surface, when i take it off no one can see any holes

 

Interestingly enough, I don't think I'll have a scraping issue unless I am on a major slope. The skid plate on the car slopes down lower than the plate (or at least I hope it does).
