well, any plywood hanging off the front of the car would be an obvious choice....

you could lose 50 lbs of interior/ventilation/etc. and keep your windows. glass and lifter mechanisms etc. ain't light, but seeing that you store your car outside, that might not be an option.

I did all of that plus a few other things - lexan rear window, muffler heat shield (it was broken anyway), rear lid spring, engine lid spring and extra bracing, 'skin' targa top, Odessey 680 dry battery.
I will probably go "stage II" this winter (LOL - that's the next 3 weeks or so) and do glass lids, cable/GT headlight kit, and start drillin' and cuttin' excess metal. I need to weigh the car first to see where I'm at now. |

On my '75 I can't ditch the expansion tank. It and the filler neck are one unit.
I plan on cutting out one half of each stiffening rib in the decklids. And cut off two cylinders. |

Lose the pop-up headlights and go with a one-piece f/g or carbon front deck lid. Use a light wt. set of "driving lights" as headlights for accasional driving after dark.

This doesn't apply to you JP. How about the driver's gut. I'm packing an extra 30 lbs. Free unless you buy a gym membership..

I built the lightest 914 in the history of mankind. Group: Members Posts: 120,304 Joined: 3-February 03 From: Jacksonville, FL Member No.: 222 Region Association: None |
This is from my August 2, 2006 entry in my blog (IMG:style_emoticons/default/biggrin.gif) ....
This question has been asked several times recently so I thought I would post all the things you could do so I can just cut/paste when it is asked again. biggrin.gif First you need to realize that making some of thse changes will change what clas you run in at your local autocross. And if it is a street car, these will effect the safety of the car. Steel saves lives- fiberglass saves weight. 1. Change the hoods, bumpers, and valances to fiberglass. 2. Switch to a lightweight fiberglass targa top. 3. Change the glass to polycarbonate 4. Remove the carpet, backpad, pass. seat, sun visors, console, 5. Remove the sound pad from the engine compartment 6. When you change the hood to f/g remove the springs and hardware. 7. Remove the fresh air fan from under the front hood. 8. Replace the heater boxes with a header. 9. Remove the windshield washer system 10. Remove the headlight motors and assocated stuff 11. Remove the arm rests from the door panels 12. Change to early doors w/o the steel beam 13. Remove the door windows and cranks. 14. Remove the heat shield which is over the muffler 15. Remove the sound deading material and any undercoating 16. Remove the seam sealer that cover the welds in the trunks 17. Some think f/g rocker panels save weight over the stock ones. It is true they are lighter but not by much. 18. Aluminum wheels. 19. Racing slicks are at least half the weight of a street tire. 20. Install a racing battery. Saves 15-20 pounds easy. 21. About half the wiring can be cut out. 22. Remove the cover plates from the back side of the brake rotors. 23. Grind/cut off all the brackets/bolts/tabs/ etc that are everywhere on the car. 24. Remove glove box and door. 25. Install f/g door skins |

( going to weigh, rather ) KT Right now it is lighter than Paul's car..... (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/av-943.gif) Trek, HP is good to a certain degree. In auto-x the lighter you can make the car with out effecting structure, the better it will do. It is a transitional thing. And you are atleast 180 lbs. heavier than anything Randal does because of your engine choices. My suggestion for auto-x is loose the weight, any place you can. JP is right floor tar is cheap, I thought you got rid of some of it all ready. I pulled 24 pounds worth of tar out of my car so far. Somebody at the factory decided I needed three layers of that carp in places (IMG:style_emoticons/default/confused24.gif) Doors are easy, if you have late models. Drop the lifts and use a strap, ala 356 lightweights. You can drill the living _____ out of your door frames, ala Peter Gregg style. Or go the Brant route and take every part weight it, and remove an ounce here a pound there. And he is still going. I think I heard the rumblings of aluminum rocker covers. I am taking all these approaches to the degree of making the car still semi-streetable. Something my wife would not worry about riding in to a social event, etc..... Balance is a hard thing to do, it is killing me right now. Oh and DN is correct, I got a good 50 lbs I can take off my frame.... But that seems a lot harder than dropping weight out of a car. But I do need to do it. |

There are lighter brake setups. Many of us have to run factory brake setups due to class rules, though.
Instead of removing seam sealer in the rear trunk, how 'bout just cutting out the entire floor? |

Arrrrhhhh! Group: Members Posts: 4,327 Joined: 16-March 03 Member No.: 433 Region Association: None |
Have you taken the front trunk springs out yet? You can use a 1x2 piece of lumber from Home Depot to prop open the trunk. (IMG:style_emoticons/default/biggrin.gif) You can do the same with the rear trunk rods. The lower pad on the dash weighs more than you would think and it is easy to unbolt. If you dont care about stock ventalation the intake box, motor, etc add up to some poundage. Muffler shield is heavy. I'm working on my spare targa top to make a race only lid.
Can you say fiberglass bumpers and hoods? |
