Here is a pic of the front with the crash bar removed:



I'll have to take a pic of the front with the crash bar in place tomorrow. My flash doesn't work.

Wrecking the front of these cars is catistrophical to begin with, just be a safer driver!

Just FYI, sagging won't be a concern on a fiberglass nose. So you won't need any structural support to hold its shape. As long as the fiberglass isn't paper-thin, you'll be fine.

Also, the purpose of the eggcrate material is to absorb energy during an impact, by crushing. Reinforcing the bumper will not absorb energy, but rather will transfer more of it to the chassis. This is exactly the opposite of what the egccrate material does.

Maybe you could use crushable grille material?

What I want to do is in a sense, re-create the eggcrate as a permanent part of the new bumper by making a web system inside the back of the bumper. I think it would help disperse the force over a larger area.

that sounds great. would rather have to buy a new bumper from you guys instead of my little one hurting herself.
keep up the great work....

Use foam inside the bumper.... this will help absorb some of the impact. Modern cars use foam to keep the shape, and to act as the egg crate in the fiero.

We could pour some foam into it and let it form-in. but even the egg crate is only 5 mile an hour bumper stop.

so pouring the foam will give you not only the best looking bumper out there but the safest as well. good work guys.... starting to put money aside to pay for one of these now....

Here is the crash bar on the front. There is a similar one on the rear. This is the actual car we are using as a model for sculpting and fitting.
