    What kind of weight reduction is possible without drastically altering the look/character of the car?

    For example, I think that gutting interior parts, cutting and removing inner fenders, acid dipping (does anyone do that anymore?), etc. take the modifications to a different place where you no longer have a factory-like driving experience.

    On the other hand, modifications like aluminum wheels, fiberglass bumpers/hood/trunk can leave the appearance and function of the car more or less in tact.

    How light have you gotten your car without turning it into Franenstein's monster?

    Obviously, this is open to some opinion. Any thoughts are welcome.

    In my case a diet could help a lot.

    I know a stroker B engine with aluminum heads, intake, water pump, and headers can weigh almost 100 pounds lighter than a small block.

    I have always thought that the first fiberglass parts to put on were the front and rear bumper. I know steel bumpers weight alot. I just wonder exactly how streetable that is at a grocery store parking lot.

      Honestly - you can cut the skin off the unibody, lay it over a tube chassis chromoly chassis, stick a glass nose on it and some aluminum tinwork, and get it down to 2500 or less race ready depending on the driveline. It would still be easily recognizable as a Duster. personally I don't like glass fenders I have to work over, fiberglass doors on a street car, or climbing over a bar to get in (back is getting tired). But replacing hardware, omitting non-essential parts everywhere, removing or "holing" bracing structure, etc, can get you hundreds of pounds looking bumper to bumper.

      yep, and you can get lexan panels and save hundreds too. and lightweight seats, tubular suspensions weigh less.

      Depends on where your starting. Here is a couple of easy mods......
      1). If you go from power to manual steering, that's 40 pounds. Plus, it frees up a lot of room under the hood (hoses, pump, brackets, belt, bigger box). Also, you can loose another couple of pounds off the crank if your replacing a 4 groove factory crank pulley with a single groove.
      2). If you have the 5 mph shock bumpers, you can remove about 35 lbs per bumper as there is a lot to remove behind the bumpers (and still keep the steel bumper). 70 lbs easily lost between the two.....
      3). Of course, aluminum intakes and wheels is a sure weight loss....
      4). Power to manual brakes will free up more room under the hood and shed about another 5 lbs
      5). If ya have the fold down rear seat, certainly some opportunities there......

      You could do a lot to lose weight in your car and still make it look like your car . My 1973 Dodge Dart weight is 2950 without me in it . And that's with a roll cage and j bars and a 360 with aluminum heads , ps steering car , Manual brakes ,727 Trans , aftermarket sway bars , 17x9 wheels .

      This is what I have done to loose weight
      Fiberglass bumpers , hood , trunk , fenders , all unnecessary latches are gone too , no crash supports for bumpers . tubular control arms strut rods , disks brakes all around , got rid of the undercoating , no heater box . Lighter seats , no rear seat . Aluminum fuel cell . Some other smaller things that I don't remember at the moment .

      Car actually should be lighter than when I weighted it , that was before the fuel cell and pin on trunk and other things .

            I'd like to see the spoiler too. I've always wondered if I could make stuff like that. I kind of doubt it.
