C3 Door VIN Sticket - Part 2

[Tom Freeman]

Reference thread at https://www.ncrs.org/forum/tech.cgi/noframes/read/76455
re the mylar sticker on the drivers door. Question was about the weights listed and the response was that they were GROSS figures with passengers, baggage, fuel, etc. That sounded right to me at the time. But got to thinking, and for me that is a job Then if this is correct should not all C3 of the same year and body type have the same GROSS weight regardless of options? The automatic is 54 pounds heavier then the 4-speed. So the 4-speed car will be lighter thus it should be able to carry 54 pounds more "cargo". But the cars have a lower GROSS weight. Appears that as the options go down, and the cars weight goes down, the GROSS weight also goes down. The logic seems, to me at least, you would have a base weight and a Gross weight for the year/body style. Then as you add options increasing the weight of the car you would loose an equal amount of cargo capacity. Now I am more confused then ever on these numbers

Tom -

I guess you'd have to ask the guy at Engineering who developed the algorithm; the computer generated the label automatically for each car, and St. Louis just took it out of the printer and stuck it on the door.

There are some who are trying to recreate the label for their cars and would like to get close to the right numbers on them. One of my cars still has the original label, another does not. Just trying to figure out the numbers to put on them.

Tom-----

The GVW rating of a vehicle is affected by several factors. One of the most important is the installed springs. For any given year, several different springs, particularly front coil springs, could have been installed in a car depending upon the installed options in that car. Beginning in the later 70s quite a few different front springs could have been used depending upon installed options.

Tom I was checking out the weights and if you have a tank sheet for your 73 the information is listed on the bottom of it and it is the same as on the blue sticker.

On my 73 w/ L-82, THM, PS, PB, AC, AM/FM stereo, & PW the label reads:
GVWR 4023, GAWR Frt 1927, GAWR Rear 2096.
To help with the confusion;
So with a GVW of 4023lbs and a vehicle base weight of 3407lbs and options weight of 237lbs my Corvette can carry 379lbs of people,luggage and fuel. So I can ride plus 80lbs of gas, about 10 gallons, and another person or luggage of 99lbs. I guess I overload the car most of the time I drive it - when I and my son or wife ride with me and 3/4 of a tank of gas.

Roger,
The 3407 is Curb weight and includes a full tank of gas. So that leaves you with 379 lbs for you, passanger, and luggage. So you can have two people of 150 lbs each and 79 pounds of luggage.
