2017 Grand Sport weight and balancing
For anyone interested. Just picked up my car and I was pleasantly surprised at what were all measured!
Car weighed 3,650 lbs with 3/4 tank of gas, 165 lbs dry weight (used for driver), Vetteworks sharkbar, 6pt harness, stage 3 aero, fire ext., ZL1 aluminum jack pocks and license plate holder. May be 1-2 lbs of junk in glove compartment.
Gas alone weighs about 90-100 lbs depending on what 3/4 on the gage means.
Weight balancing was 49.5% front, 50.5% rear, which will vary a bit with gas.
Nice job GM reporting it as it is in real world!

Stock wheels and tires?
For comparison, my 2015 C7 Z06 3LZ weighed 3559 with a full tank of gas on stock wheels and Cup 2 tires. No driver. The only modification was converting the standard iron brakes in front to the AP Racing endurance kit.

The more important balancing number was the cross-balancing which was 50.6%....outstanding! Based on the above, I'd estimate GS's dry OEM weight to be an actual 3,350+/- Lbs.
3559 for Z-3LZ makes sense, with supercharger, gas and 3LZ weight add-ons.

Gotta admit, it's mildly upsetting to see the SS 1LE Camaro weigh less than the Corvette Grand Sport. C8 will certainly be dropping pounds, I think it's an inevitable strategy that must be employed. I'd assume GM will eventually attempt to make all the panels out of carbon along with mass production of the entire body out of CFRP. I think a lot of this Bowling Green renovation has to do with the future body panel production.
Since the development of C6 ZR1, the process of creating panels out of carbon has gotten faster, going from fast autoclave processes to a type of pressure press. They also hot bond panels at ambient temperature, versus bonding them and oven curing the adhesive.
Hopefully we see the same percentage of mass drop on C7 to C8 as we saw from 5th to 6th gen Camaro.

I've never seen anyone go on a diet to get the weight down. I have seen people pay a lot for titanium lug nuts though.

So from the factory with you in the drivers seat the CB cross weight was 50.6%? Wow i had no idea any manufacturer was sending out of the factory with corner balance that close. Awesome!
