Looking to get front end weight down.

I have a fiberglass front bumper, here's what I did to the brackets. What you see in the photos took 5.6lbs out of the brackets. I have since removed the outer brackets.

I wouldn't worry about under hood aerodynamics from removing the inner fenders, there are thousands of Mopars at the strip every weekend without them.
