Weight of fiberglass parts?

[87we410877]

I searched and couldnt really find anything. I was thinking of putting fiberglass bumpers on my WE4 and was wondering how much weight it would remove both front and rear. I would be re-installing the rubber strips on both.

Next is, how much does the glass hood and trunk remove? Thanks alot.

Personally, I would keep the stock steel bumpers and ditch all the weight behind it. It will at least do something on impact where the fiberglass will be useless.

I have cut the rear bracing to the point where I used it as a way to hold the bumper to the support brackets. I also went aluminum brackets to ditch even more weight.

The front bumper has a Canadian brace mod that will shave off a bunch of weight and keep the stock steel shell.

Here is some of my info on body parts

Chopped up rear Bracing 4 holes away = 23 1/4 lbs
Left over Steel Mounting Braces = 5 1/4lbs each = 10 1/2 total

Im probably going to go with the entire glass bumper and ditch everything metal behind it. The car is rarely street driven and even more rarely track driven. After i run it i may take them back off and re-sell em and install the stockers. I was looking to get 200 lbs from the bumpers, hood, and trunk. I want to get down to 3100 or less lbs. Im at 3460 now.
