I find the weight of the '78-'81 front bumper ridiculously heavy and a hinderance to better handling. The issue is not the urethane and fiberglass bumper cover, but the steel structure underneath it. Here is a picture: I removed it and weighed it at 47.8 pounds. Adding the hefty brackets that mount it to the subframe and the associated hardware brings the total to 67.6 pounds. I don't know how much the urethane/fiberglass bumper cover weighs, but it doesn't seem too bad and I estimate 15 pounds. The total is likely double that of a modern car and perhaps even of an early Gen-2. Unless members here have better ideas, I plan to use my plasma cutter to cut away about half this structure. I have examined what the bumper cover needs and it is mostly just the top plate; also vertical sections of the right and left sides. I plan to cut the middle vertical section out completely as I want to make the lower grille functional for better cooling. I had hoped to replace the urethane bumper cover with a stiff fiberglass one, but I cannot find one. NPD lists one in their catalog but it is out of production. I don't want a race-only one-piece fiberglass front and fender combo. Basically, I am trying to lighten the car and am open to all suggestions. So far I am also planning on a Kevlar hood with billet hinges. I see that fiberglass inner fenders are available. If aluminum fender or doors were available, I would splurge for those. I plan to install the Detroit Speed front clip this winter, regardless of whether it saves weight; I already installed their Quadralink rear suspension. Thanks. I look forward to any feedback and suggestions. Especially if someone has already done this.
