"ALL THIS TALK ABOUT HORSEPOWER THIS AND HORSEPOWER THAT. WHEN WILL PEOPLE REALIZE THAT HORSEPOWER ONLY SELLS CARS??? TORQUE IS WHAT WINS RACES"!!!!!!!!!!!
Is this for the a street car? I don't recommend doing any of that.
For a strip car, the bumper covers will sag without using another type of support system. People opt for using chromemoly supports. Much less weight than the bumpers but still required to prevent sag.
Side crash bars...
Here's a quote from a mustang website.
#5. Door Crash Beams - Ever saw a strip only Mustang with the door crash beams removed for weight savings? This is alright for a strip only car with a side bar type roll bar but for the street - NO WAY!! Not only are they there for crash protection, but they give much needed rigidity to the sheet metal door skin. By the way - total weight savings is under 10 lbs. per door.
Those crash bars are a huge PITA to get out without cutting them.
If you have a cage, go for fiberglass doors so the steel ones don't deform.
I'd look at other ways that are safer to reduce weight. Tubular K-member, seat delete, gut it?, lighter wheels, fiberglass hood/hatch, etc.
"Research is what I'm doing when I don't know what I'm doing".
In my coupe that I had I pulled the front and rear suports out and rear bumper didnt' sag but the fron one did a little bit BUT I didn't have the the fender brackets on either (they was not there when I boutht the car) and I believe that made the bumper sag b/c the fenders bow out some
Now on my 87 GT I have I do have the rear suport out and the bumper does not sag and it took 27 pounds out counting bolts and all. IMO pulling the front isn't worth it b/c it's a fiber glass support and it's only 10 pounds. The door suports I have no clue about.

I've got the front bumper out of my car (an 84).
Car runs 10.85 @126 now and the front bumper does not distort.
Front bumper weighed 42# in my case.
This is a strip only type car and I wouldn't even bother with the door braces if they are only 10# each, I'lll use the braceing for the nite I bang off the railings at the strip.......
