Put the car on your race car scales and get an accurate weight. I weighed my Z51 and the numbers were very close to GM published weights.
The Z06/Z07 with CF wheels dry is 3434. Then add about 90 lbs for fluids (oil - 8 qts, DCT fluid, water 6.5 gal - brake fluid etc.) and with 9 gal gas (55 lbs.) you get 3579 lbs. Save 20 lbs with Lithium battery and use light weight forged wheels (+20 lbs) and I expect to come in around 3580 lbs with half a tank of gas for a 1LZ Z07 coupe.
I think you are a little light on the fluid weight - I think it is a lot more than 90 pounds - Like at least 150 pounds.

Thanks, I don’t own race scales and just want to do a one time measurement, but three cars (458, STO, F8 spider). I’m just curious how close to Ferrari’s published numbers I get. And the Lambo, too.
Maybe the shop has them. Thanks for the suggestion.

I am pretty sure my numbers are accurate. Look at the C8 base model. Dry weight is 3366 lbs and curb weight is 3535 lbs. - these are published GM numbers. That is a total of 170 lbs for fluids and gas. Gas is a full tank, weighing 18 gals at 6.1 lbs/gal total 109 lbs. That leaves 60 lbs for fluids. When I weighed my 1LT Z51 the numbers said they only had about 15 gals in the car and fluids were 80 lbs.
These fluid numbers make sense because the base C8 holds 22.7 qts (~48 lbs) coolant vs Z06 holds 25 qts (54 lbs). 2 gals of oil is 14 lbs, trans fluid is ~12 qts (21 lbs), no power steering fluid, ~1 liter brake fluid, windshield washer fluid, what else is there? That is 89 lbs plus the small misc amounts, so I think the 90 lbs or 95 lbs max for Z06 fluids is accurate and agrees with my Z51 weights well.
Remember i added 9 gal of gas, half a tank at 55 lbs. separately.
Interesting... in the first drive video posted in another thread they talked about how they firmed up the engine/trans mounts. Appears they didn't even need to use balance shafts on the LT6. They literally out-engineered the rest of the world.
either that or cut costs and said when people come in with rattles and vibration concerns? Prognosis?? Normal.
End of story.
If its too much for some? They couldn't care less. Another 10 will lime up to buy it..
Gm can do no wrong with this car.
I can't wait until carlisle I'm renting a C8 since my Z06 is maybe 6mos out from being ordered according to my guy. 3yrs plus wait.. another 8 9 mos ain't gonna kill me but the anticipation of driving this new gen vette is lol..

I get what you are saying - There is a picture of the Yellow Z06/Z07 coupe that was making the dealership tours that showed a 3703 weight in the door jam. I am not sure if that is a 3LZ, but it did have Carbon Revolution Wheels.

That makes sense. The regular non z07 / cf wheel cars are going to be 3800 lb cars. So most cars you see around will be 3800 lbs.
Ya it’s porky considering the c7 z was 3500+ ish. I remember trackers here saying, when the gt500 was getting praised for its track manners, saying it’s too heavy at 4100+ lbs etc etc. Gonna burn through consumables and tires and brakes blah blah. What about this car? 3800 isn’t all that much better. This won’t burn up your consumables budget on track?
Those buying this car to drag race are the ones who’s choice is the problem, not the car.
If "the car" didn't care about drag racing, it wouldn't come with launch control. Every performance car manufacturer considers use in the most accessible and most participated form of motorsport.

Just curious where all those people are now?
We've haven't gone anywhere... car is far too heavy for my liking, but I can't afford a GT3 Porsche and it won't be a dedicated trackday car.
porsche gt cars are now close 3300 lbs without light weight $$$ packages and wheels. even caymant gt4 which is a small car weighs over 3200. vette under 3800 is fine. will wear out tires and brakes if track hard and often but to be expected with the porsche gt cars too
Amazing how this vehicle has been in the works for several years and is about to be released and there is still "back and forth" on weight and still no 'Ring time.
^^^
GM has NEVER...I'll repeat...NEVER published a 'ring time for ANY car that was not a PRODUCTION car.
Since production is just now starting, I'm not sure what you're expecting.
I think you are a little light on the fluid weight - I think it is a lot more than 90 pounds - Like at least 150 pounds.
He did the math and came up with 90 pounds (excluding 9 gallons of gas, which he noted). Maybe you should do your own math and see if you come up with 150?

You have the numbers right...the "angry mob" decided the car was 3,700 pounds plus WET and by God, they're running with it (instead of, you know, actually doing the math like you did).
PS. I just did the math also...you ARE correct

GM put the world on notice?
More like, put the world on standby.
The only "back and forth" on weight is on THIS forum. The car's DRY weight (Z07 Coupe with CF wheels) has BEEN known (it's 3,434 pounds).
See post #80 for the WET weight.
PS. You'll note that this thread, with the DRY weight, was started on 10/26/2021 so I'm not sure why there's ANY confusion at this point.
There will be NO 'ring time until (and if) GM gets a PRODUTION Z06 over there to do it.
As far as a Nurburgring time being needed to sell the car, the 2011 C6 ZR1 held the record for a time and you could buy one all day long, with a DISCOUNT back then.

@jimmyb I do not have to do the math - GM already has. Does this help you? Do you think GM would post false information inside the door? See the door sticker below for the wet weight of a C8 Z06/Z07 with Carbon Revolution Wheels. I mistakenly said yellow car - It was the Red Z06 going around to dealerships (My bad). The picture below is the tag from the inside of the door of the C8 Z06/Z07 with Carbon Revolution wheels.

The fluid amounts I used were out of the GM manuals and documentation. The weight of water, coolant, oil, gas etc, are well known values. So my numbers are correct.
The 3434 I used for a 1LZ and added 95 lbs for fluids and 55 lbs for 9 gals gas gives 3584 lbs. The 3700 lbs is full fuel so an additional 55 lbs fuel. Then add in the weight for a 3LZ because I think most of the tour cars were 3LZ and that can add another 50 or 60 lbs. That is 3700 - 55 - 60 and you have 3585 lbs. In this way I think the numbers are consistent. All the extra speakers, seat motors, mirror motors, front lift, cameras, seat heaters, vents, mirror controllers, wiring, sensors, leather wrap everywhere and whatever else adds up.

This door jamb sticker shows the HEAVIEST a Z06 can be, in my opinion
We KNOW the dry weight of a Z06 with aero and CF wheels is 3,434 pounds. Now, do YOU think that GM has a DIFFERENT sticker for EVERY Z06 made, taking into account the options that this particular car has or doesn't have which would change the GVWR. I truly don't know, but I bet the GVWR sticker is the same on all the cars, regardless of options.
Can some folks with Stingrays post what the GVWR is on your sticker and what options you have?
OR
Someone with a C8 HTC with Z51/Magride, 3LT, Front lift post their numbers (PS. The GVWR sticker is on the drivers door, the tire sticker is on the drivers door jamb)
My car:
2021 HTC: 2LT (GT1 seats), base suspension, NPP, Painted Roof/Nacelles
The numbers are: 4,087 lbs, GVWR. 423 lbs. combined passengers/cargo. Which means my car is 3,664 pounds, based on the sticker.
If someone posts with a Z51/Magride, 3LT, Front lift, with the same numbers, then we'll KNOW the stickers are NOT taking into account the options, since we KNOW a Z51/Magride, 3LT, Front lift car is heavier than mine
PS. The 3,434 dry weight was published 5 months BEFORE your sticker picture.
