My 4 cylinder PT Cruiser weighs more than my '80 Vette, I don't think they are that heavy, mine come in at around 3100lbs

..... EDITED with my mods too!
by replacing the:
a.) 50 Lb rear steel spring with an 8 lb composite,
b.) aluminum wheels (if you have steel wheels),
c.) dumping the very heavy monolith cat for no cat at all,
d.) dumping the AIR pump and hardware,
e.) STANS Tri-Y headers instead of the heavy cast iron manifolds,
f.) aluminum water pump,
g.) aluminum intake
h.) eliminating the A/C compressor if you are so inclined,
i.) Tremec 5 speed manual
j.) Mini-Starter
k.) Evap removal:
l.) Spare tire removal
m.) jack removal
n.) 200w speakers in the rear (heavy magnets)
You can shed lots of weight pretty fast .....

Yep!
I did these plus a bunch more. Especially on an already lighter 1980 
forgive the mess & the car cover.

I think that this thread should be merged with that one:

Does anyone have that webpage or article that tells the base weight of a particular C3 and then has the different weights of every option that way you could total up how much your C3 weighs?
I see that '73 had a curb weight of 3416. My question is that a big block/small block, ac/or no ac, and so on...
So, I think if someone has a link to that website, it would be quite useful for anyone is wants a rough estimate of their actual weight.

my car is 3150lbs ... without me in it.
LSx baby
I plan to remove my A/C, evap and condenser. I wanna keep my heater though. maybe 30lbs?
And that HUGE front bumper support?
I wonder if I can lighten it some how?
maybe 40-50 lbs?
I have fiberglass rear spring, lighter wheels, no mufflers (LOL), FULL STOCK INTERIOR.

The 1978 seems to weigh the most at 3572, followed by the 79, at 3503, the 69 weighed 3245. Figures taken from the Corvette Black Book. There is a lot of steel in a Corvette. Even the doors have a metal frame in them. I was suprised to learn how much more my 77 weighed then my 1986.

I did last summer. I think it was 3029 lbs (or 3059?). Very little fuel & me not in the car. There was another thread that we all posted our weight last year.
it was kindof like Americas biggest C3 Loser
But, the good thing about the 80 is it is a few hunderd pounds lighter than a mid-year C3 right out of the box.
pps... My car originally came with the Lg 305 CA engine....

I apologize for bumping a very old thread but I wanted to keep all the info in a similar place.
I've used search and google to research weight reduction and curb weights and read all of the threads from Bee Jay and Panic
My 1980 corvette weights 3,108 currently without seats, door panels, radio, or mufflers.
Does that seem about right? Stock curb on vettnet was 3,282 or so (give or take a few options)
My car was on a scale for the 3,108 so I have to believe it's a very accurate reading.
If so I can't imagine how I wouldn't be able to hit my goal of 2,700 lbs.

I was just doing a curb weight search also........2009 thread...LOL!
It has good info though.
A racing friend told me that 100 lbs. of removed weight is equal to modifying the engine in order to gain 10 more H.P.!!!!
Obviously (like the members said)-----removing 300 pounds to gain 30 h.p. will save a person about $2,000.......or just install aluminum heads, better cam and lifters, and headers to drag around that spare 300 pounds!

Weight
I am well familiar with the formula for that racing theory.
At a 1980 curb of 3,282 or so and 190 brake horsepower that's 17.2736lbs carried per 1 horsepower.
So if I had a goal of 2,800lbs let's say...dropping 482lbs...a car without the weight reduction of the same year and options would only need to gain 27-28 horsepower to be similar in power to weight.
But it's not all about power for me...it's about how I'm not going to drive a corvette with a fiberglass body that weighs more than my s2000.
It's not that I'm neglecting the 350 motor either, it was rebuilt by the previous owner so I'd rather get the rest of the car where I want it before hand. When I get an itch to go fast I can take a ride in my Evo which has over 400hp at the moment.
It's cold in Wisconsin right now so I am okay with stripping down the corvette in the garage for awhile

My since sold 2009 Z06 was closer to 3260lbs about 80lbs lighter than my 72 LT-1 coupe with T-tops and rear window out and 180 lbs of weight in the driver seat during corner weighing/balancing. Unless your 2010 Z is some kind of stripped Vette, I cant imagine its really quite that light.
C3 Vettes gained weight as the model aged, after 72, the 5MPH bumpers and options load shot the weight of these cars up considerably. Some of this gain can be remedied when your re-skin the urethane bumpers, leaving off some of the under structure can save considerable weight but, will make the Vette less safe in impacts, depends on what you value. If you really value safety might I suggest a Bricklin........
