Let's say it (the Z06) does show up at 2022 LL, and it does a 2:39-2:40...
Will your answer be: "It should have done a 2:37"?
The easiest comparison is C7 Stingray to C8 Stingray at LL: The C8 Stingray was 4.8 seconds faster. If the C8 Z06 can match that difference, that puts the C8 Z06 in the 2:39's

It will not do well where well is defined to be better than C7 ZR1, 992 GT3, 991.2 GT3RS. It will do better than C7 Z06. GM knows this and I don't think they'll be eager. Look at the top 10 in LL. Look at their 1)Weight, 2)Power, 3)Downforce. Actually, I looked at the list and I am saying the only car that's heavier than C8 Z06 is GT500 (Which has #16). All other cars 1-15 weighs 3600 lbs or less, has more downforce, and has equal or better power (if the car in question is in the heavy side). I think the heaviest car in that list is Turbo S (3660 lbs) with 640 hp and AWD but a lot more torque.
Unfortunately LL is all about the lap time. There is no "emotion" and "sound" metric that gives you extra points.

I am 100% confident the C8 Z06 will be at Lightning lap. The Corvette is engineered to dominate the Lightning Lap the way the 911 is engineered for the Nurburgring. There’s a reason Corvettes always dominate Porsche at the LL, it’s very important to Corvette and just another lap time to Porsche. The results bear that out.

C7 ZR1 is 1 second from 992 GT3. One of them is 755 hp, the other is 502. One is 715 ft lbs, the other is 346. Do you see how much more power Corvette needs to keep up with the Porsche? This time around, Z06 is heavier than the ZR1 by 150-200 lbs, makes 80 hp less, 270 ft lbs less but wears better tires and has better transmission. I'd wager a bet that VIR isnt a track where A8 vs DCT will make more than 0.2 seconds of difference at best. I watched the C7 ZR1 videos, both LL and GM's own laps and transmission did its job flawlessly. Having DCT in Z06 doesn't make much of a difference.
Now the biggest disadvantage of Z06 in VIR isn't its weight or that it doesn't make enough power to make up that extra weight. It's the gear ratios! VIR is a track that likes high speeds. ZR1 hits 170 in the long stretch I believe (or 172). Well guess what, post 140 the Z06 hits a wall. So those fractions of seconds will turn into seconds in the long straight where the difference between 172 and 159 will make a big difference (I doubt C8 Z06 will break 160).
I am willing to bet my forum reputation here that it won't beat 2:40 in any configuration when driven by LL drivers. When driven by GM's factory driver or a race car driver, it may break 2:40 but then apples to apples GM's did lap VIR 2 seconds faster than LL with C7 ZR1. So we would need to see sub 2:38 if GM does this lap.

We can go back and study every year where that happened. It wasn't "arbitrary" Corvette always destroying Porsche. C7 Z06 did beat 991.1 (not .2) GT3 because it came with near slick Cup tires vs Porsche's much more Pilot Super sport like, older generation Cup tire. Porsche's Cup tire for 2015 GT3 and Corvette's for C7 Z07 were very different. Then there was the fact that C7 Z06 had 175 more horsepower and 300 ft lbs more torque to make up for 200 lbs more weight. So it beat the 2015 GT3 but that car had a bad engine, made only 475 hp, low downforce, honestly **** tires that didnt belong to a GT3 that clearly Porsche's development budget didnt allow to work with Michelin (and Corvette did the opposite and spent a ton of money developing C7 Z06 only Cup2 ZP tires which that bet paid off). The tables were turned however with the 991.2 GT3/RS cars. Better tires, more horsepower, a lot more downforce.

It probably cannot obliterate the GT3 by 5.4 seconds the way it did in 2015, but there’s still plenty of room for a great performance. There’s only a 3 second difference between the 2019 GT3RS and the 2015 C7 Z06 so if you believe it can beat the C7 Z06 you pretty much have to believe it’s competitive with the 991.2 GT3RS.
I am 100% confident the C8 Z06 will be at Lightning lap. The Corvette is engineered to dominate the Lightning Lap the way the 911 is engineered for the Nurburgring. There’s a reason Corvettes always dominate Porsche at the LL, it’s very important to Corvette and just another lap time to Porsche. The results bear that out.

I put my money where my mouth is. You guys dont realize that I might be criticizing the vette but I have $140k invested in a ZR1 + another $175k in the Z06. The only reason I say what I say is because I want people in GM to take notice of what we as the community think so they can improve their products. I firmly believe the N/A powerplant decision in Z06 was part of endless comparisons C7 Z06 had against a 911 GT3.
