Ok so basicly i need to know were the big weight items are in my 86 i have the full interior out all the dash is gone what else can i take out to get this car under 3000 pounds without taking out the glass and stuff please any input would be helpfull

 

Do you plan on this being a track only car or do you plan on using it on the street, too? If just for the track the doors are super heavy but they act as a reenforcement point on the unibody and I would only replace them if you were running a 25.5 roll cage, if you are go with fiberglass doors. As for the rest of the car replace the front fenders and hood with FG or if you could afford it carbon fiber(might have to have those made custom for you). The front suspension go all tubular aftermarket K member and control arms. You can also strip the undercoating off and just paint the bottom of the car. I can't think of much more right now. Sorry if I didn't help.

 

Hood, yes, fender no. The stamped steel fenders are probably lighter than fiberglass ones plus fiberglass fenders, if you can even find just fenders, will not be a simple bolt on item. A frame structure is used to hold fiberglass fenders on.

A simple search produced this thread

The main areas of reasonable weight cutting is

1 Air Conditioner
2 hood
3. Aluminum heads/Aluminum LS motor
4. Lightweight wheels
5. switch to a T5 (good luck with that... I wouldnt recommend it)

The first 3 MIGHT net you 100 lbs off the front of the car.

You can get lexan hatch glass, to cut a LOT of weight off the rear, but these cars are already too front heavy. No sense in taking much weight off the rear, really.

Beyond that you better look into that thread. You'll probably be endangering yourself by chopping out door reinforcements and bumper supports and whatnot. Removing the ground fx will get you pretty far, though.

 

THis is a full out race car so as of now I have the full interior out including.carpet heater box all the door pads console basicly its just a driver seat in it removed the fuel tank now has a five gallon cell it has a 355 aluminium headed motor and ford nine inch rear I am about four tenths off the number I wanna be before I gutted it but I dont think I got 200 pounds out of the interior

 

You can gut the doors. Back when my car was still stock, I took off the power everything doors and put them on a scale. 105 pounds each. I picked up some non power option doors and gutted them as much as I could. I kept enough inner steel to hold the window regulator, cut out the crash bar etc and got the weight down to 65 pounds each.

My fiberglass doors are around 25-30 pounds each but they're not cheap.

For a gutted out race car, the best advice is to remove everything not required for speed or safety. My "race weight" sitting on the starting line is 3020 pounds and I weigh around 170 pounds. My car also has a couple of hundred pounds of roll cage tubing in it and a BBC so you can get an idea on just how gutted it is..

Replacing the windshield with Lexan removes around 10-20 pounds. Side glass I can't remember but you would be removing glass, regulator, tracking etc and replacing it with fixed Lexan.

Rear window and deck lid shaved at least 100 pounds off the car. 100 pounds is 100 pounds and it doesn't matter where it is on the car. My car is still nose heavy and I've carried the front tires in the air for about 80 feet earlier this year. My rear window is some thin Lexan and the deck lid is a sheet of aluminum held on with Dzus fasteners. The window doesn't open and the deck lid can be removed to access the battery if required.

Get rid of the front and rear bumpers. That's dead weight you don't need.

 

the problem with the lexan is that i belive that classes i wanna run with it requires all glass windows i think now as far as front and rear bumpers what do you mean by that is there metal under the plastic bumpers?

 

The plastic bumpers are just covers. Take them off and you'll see large heavy honeycomb bumpers behind them. Unbolt and remove the bumpers. Reinstall the plastic covers.

Even if you're required to run all glass, there's still a lot of weight that can be cut out of the doors.

 

I am gonna cut the doors up this week and pull the bumpers do I need to fab brackets for the nose due to lack of support now ?
