It would be cool if GM would just publish the technical specs. Information must be on constraint. Putting the World on Constraint.

I'd like to reiterate my calculations are SPECIFIC to and related to the C8 Z06 Z07 1LZ Coupe. The lightest of them all.
A lot of folks just stop at the CF wheels and carbon fiber brakes.
Read the specifics on the C8 Z06 exhaust system. That alone is another 20 lbs lighter than the SR exhaust system.
The Z07 suspension is visually lighter as well. Not saying it's definitively is but it's obvious they went with different materials and mass distributions.
Want to be super detailed..? Add the carbon fiber Z06 steering wheel.
The curb weight math is easy! It just takes concentration and detail.
Again, there is no way a dry C8 Z06 Z07 weighting 3434 ends up weighting more than 3700 pounds resulting in a theoretical fluid load of more than 266 pounds!! No way.
If you know the ring and you know where the gas station is you can do a warm up lap and a fast lap with the car weighting approximately 3560 pounds!
IMHO the C8 chassis architecture is a 'payload' architecture. Both in terms of power and of course in terms of comfort features.
The car can go the other way as well. The C8 Z06 GT3 is already listed at 600HP and I am willing to wager it will be 3200 pounds max.

But majority of people who opt for Z07 and CF wheels will want at least 2LZ if not 3LZ. No one wants to spend 150k without the luxury of those trims. After all, this isnt a stripped track car and this is what Corvettes are known for, yes? Its like buying a GT without A/C or radio. It can be done but no one in their right mind would do it. I believe you that 3434 lbs dry weight cant be 3700 but I dont agree that will be a common spec. The heated and cooled seat feature alone will weigh close to 40 lbs for both seats. Who is buying a Corvette for $150k without that basic feature?
The base weight is 3434. Fluids as a few of us have accurately laid out will be 90 - 92 lbs and 18.5 gal of fuel is 113 lbs. With a lithium Braille battery and light weight forged Al or magnesium wheels I will come in at 3640 with full fuel and 3590 at half fuel load.

My 2020 Z51 is a 1LT and is at minimum weight - no options that add weight. My Z06 will be a 1LZ with no weight adding options. No interest in heated or cooled seats, dont want the front lift, dont need cameras, dont want folding mirrors, dont want heated steering wheel etc. It is not about money, my boat cost so much more than my cars. I just like to have the best performance optioned car at a minimum weight.
The base weight is 3434. Fluids as a few of us have accurately laid out will be 90 - 92 lbs and 18.5 gal of fuel is 113 lbs. With a lithium Braille battery and light weight forged Al or magnesium wheels I will come in at 3640 with full fuel and 3590 at half fuel load.

I find my base 1LT seats comfortable and I dont like the complexity of all of those creature comforts - I like a nice sound system and then can do without all of the heated, cooled, powered stuff etc.
For the best cornering experience I get in my formula car, 1190 lbs with driver, 3/4 inch ride height, big slicks and wings. 2.5 g in the corners and a proper 6 pt harness in a cockpit that properly supports you in high g corners. And tires are way cheaper than Z06 tires will be.

I agree about the heavy car, but thats what you get for $125 - 130K. On track I always run with minimum fuel for a session and top up for each session, so the car will be closer to 3565 lbs.

I considered a 1lz 8z. Would like to save some money. IHowver, I feel I really want the data recorder and video, and I also love the rear view camera. Having good rear vision to aid situational awareness is key, but I must say that I did a few events without when my camera crapped out and the rear mirror view was better than I thought even with the high wing. Finally, I do like the comp seats and the seat belt cinch feature really holds you in. Moving the electric seat back and forth you can cinch the belt tighter than you ever could in a harness. But, to do this optimally it really helps to have the memory feature to return the seat to its optimum position. Now none of these features are deal breakers, and I’m sure there are after market solutions, but at the end of the day I found it was just easier to check the 2lz box. And then, of course once your at 2lz it’s easy to say what the heck and make the small leap to 3lz. That’s what I did on the base, and it’s what I’ll probably end up doing with the Z.

Z06 dry weight with CCB's and carbon wheels was stated as 3434 lbs. That of course may change when actual production models come out, but that gives:
Z06 dry weight with CCB's and aluminum wheels is 41 lbs heavier so 3475 lbs
Z06 dry weight with iron rotors and aluminum wheels might be another 30 lbs heavier so 3505 lbs.
Add at least 220 lbs for all fluids and you are over 3725 lbs curb weight. It is not going to be lighter than a Z51 which is in the range of 3650 curb weight. A Z06/Z07 with a 1LZ package and CF wheels might be 3650 lbs, maybe.
Light weight was obviously not a design goal of the C8, unfortunately.

That is more than the Cadillac CTS 5 "four door" sedan. GM definitely made sacrifices in order to try to market a "bargain" sports car. There are two audiences here.
The first and minority are track guys, who may be disappointed with the tires if nothing else. The second, and much larger group, seldom, if ever, go to the track. They are looking for a nice daily drive. I suspect they will not care about weight or top speed or anything else, except they now have the latest C8 Z06 and a nice daily drive.

Just curious what the guesstimated replacement cost is for the OEM tires that have to carry all this bulk and still somehow manage to get the car around a corner with some semblance of grace.
There's no free lunch in this world. These tires gotta be pricey.

PS4S ZP are $464 front and $671 rear = $2,270 for the set
The Cup2R ZPs aren't on there yet, but a Cup2R non ZP 325/20/21 is $900 for one tire.

I posted a thread a while back. A set of Cup2Rs will run you 3500+ with balancing. They will last 5,000 miles in street if you are very gentle with them. They are not like regular cup2s at all. Even the wealthiest people I know who regularly track expensive cars have given up on them after a few tries.
