I want to put my car on a diet. Who has done this, starting weight? Ending weight?
I'm deciding to put my Monte Carlo on a diet. Recently took a trip to local landfill to borrow there scale for a minute. My car weighed 3800lbs with me in it. I'm a buck-75. That puts the car @ 3625lbs. Still heavy I'd say. I never considered how much exrta stuff I had in the car. I mean cargo. The trunk is used for storing old parts and unused stuff, broken posi, new kyb's, another battery, factory starter, and so on. Well, I had 325lbs of cargo. I had no idea that stuff weighed that much. Once removed, the gross weight is 3300lbs. That is better that I thought. Up until now,it was believed by me that these cars are heavy, and there is nothing that can be done about it. I am now wanting to removing more weight from the car. Fiber glass hood to replace metal one, get rid of the power bench seat, I'm sure it weighs at least 125lbs.
What is solid hotrod gross weight? Is lighter better?
What have some of you done to shed weight? Would love to hear some stories and advice. :D :D :D

lighter is always better at a acceleration standpoint aswell as fuel savings standpoint.
I helped shave about 750 lbs on a 53 chevy ( tubular frame- fiberglass nose-
tubular A arms) list goes on and on.

You can chuck the creature comforts;

A/c ducting, compressor, belts & brackets.
Power steering gearbox, pump, tank, hoses & brackets.
Power brakes booster.
radio, antenna & cable.
Carpets & floor mats.
Spare tire, Jack & handle.
Smaller battery.
Smaller radiator.
Lighter rims.
Shaved bumpers on some models.
Custom exhaust.
Remove chrome trim.

You need to consider what the intended use is, is it worth dumping the creature comforts if it is a daily driver?

Power windows, locks, seats, sound deadener, insulation, cast iron heads, manifolds (intake and exhaust), go to lighter wheels. Depending on the year of Monte, the 73 and newer have a lot of extra weight in the bumper assembly's, some of the 80 Monte's came with aluminum hoods and deck lids, they will work on the 78 to 80 cars.

re: I want to put my car on a diet. Who has done this, starting weight? Ending weight
All thats left of the ac is whats on the firewall and condenser. The wheel wells have been removed. lots more room! I'll start by removing the ac blower motor heater core area first. I just saw a cover that uses the same bolt holes on the firewall. I've been wanting to do this for a while. Same with parting out the bench seat and interior. Once I do it, I've made that commitment to the car, though. No more getting the wife and baby in it!

weight loss
I weighed my 84 Monte Carlo at the track two weeks ago and it is 2850 without me in it.You can look at my journal "84 Monte Carlo" to see how it is.

aluminum heads, block,flywheel, lw crank, rods, pistons, lexan windows, aluminum wheels, titanium fastners, carbopn fiber body pannels, etc only your wallet will determine the amount weight you cut out...

Replacing the bumpers with fiberglass replicas is worth at least 100 pds. Getting all the tar sound deadener out of the car is worth another 150 pds usually. Factory seats weigh another 100pds, you may be surprised to find the carpet weighs another 50pds too.

One of the heaviest thing on a car is the glass, kind of need the front windshield as a minimum though. To give you an idea how much you can lighten a car, I brought my 81 Mazda RX7 from 2400pds factory to 1900 pds just by doing the items listed above...and that was a small car!

i once took a hole saw to the inside of a nova and put holes behind most of the interior trim panels i thought i could offset some of the weight of interior panels and still have a decent looking interior

I have always wanted to remove the shock absorbing mounts for the bumpers and replace them with something lighter and simpler - there's got to be significant weight to lose there.

A power bench seat you say? Gawd, that's got to be heavy. Helped a friend pull the power seats out of a '70 Lincoln and we thought we'd missed some bolts. Nope - it's THAT heavy!

Nothing will go as fast & easy as your first 325 lbs...

It just depends on how crazy you want to get an how "un-user friendly" you are willing to deal with.

Tubular upper control arms are lighter then stock. You could also ditch the sway bar if you aren't concerned with cornering (or crutch it with stiffer springs). Yank the entire dash all the way to the firewall and make a barebones aluminum dash panel. Seats would be a biggy. Also get rid of your hood pivot / spring assemblies and make it a lift off fiberglass piece. Aluminum water pump is a few pounds and cheap, mini-starter also takes weight off the nose and is a good bang for the buck. Biggest weight saver off the front would be aluminum heads and intake - also dump cast iron manifolds if you have them and go to headers. Calipers can be purchased that are aluminum instead of cast iron. Replace the bumper with an aluminum one if possible. If it's a metric car some of them were built with aluminum core supports - you could find one of those and also go to an aluminum radiator.

I'd be more concerned with nose weight then tail weight - most rear wheel drive cars are already pretty front weight biased.

Good luck with your project and think twice before making any "weight reductions" you can't easily put back if you miss them!

Your laundry list is growing, one thing I can add is removing the crash bars out of your doors.

espo1980 10-08-2008 04:02 AM

Thanks for all the comments. weezin355 good tip on the door weights. Any other weight that could be hiding in the body?

espo1980 10-08-2008 04:15 PM

Never heard of aluminum core supports, what years were they used? i am also thinking of removing the heavy inner front bumper. It's a lot of bumper. It seems the only significance is for front impact. Will removing this jeopardize the integrity of the frame? Has anyone dealt with this? What significance would a replacement aluminum bumper have?....Just there to bolt the nose up, or needs to be as strong as the steel piece. Any suggestions are appreciated.
