I drive a Superformance Cobra with a 630 hp 482 alum big block, that is what you get with a high horsepower vehicle, it jumps, dances, and laughs at you. Perhaps a Grand Sport would suite you better

Agreed. I had a 2016 Camaro SS and now have a C7 Stingray. Same motor and the Camaro put the power down much better. I attribute it to extra weight and possibly the coil over suspension vs leaf spring setup. All the reviews of the Camaro ZL1 seem to indicate that its chassis and extra heft tame the LT4 and enable it to put the power down much better.
I slip and slide in my base Stingray and hear the Z06 with so much low end torque makes it hard to put the power down but the Grand Sport gets praises for being the more balanced Corvette. That 460/465 in the LT1 matched to the Z06 chassis suspension and tire seem to be the sweet spot.

Because of limited traction, there's a point of diminishing returns in power to weight ration for the street. The real difference shows up at a drag strip or the faster road courses like VIR or Willow Springs GP. The C7 ZR1's stated 0 to 60 mph in 2.85 seconds, translates into about 0.96 g forward acceleration, so using that as the limits of traction, and using a manual 7 speed transmission for comparison, the ZR1 can maybe hook up or close to it in 2nd gear under the drag strip conditions for the 2.85 second number, but probably more like 3rd gear before it can hook up on a typical street. This would mean a C7 ZR1 would pull a C7 Z06 slightly in 2nd gear, but not really pull away until 3rd gear, so the Z06 and ZR1 would be close until around 90 to 100 mph (shift into 3rd with manual). The difference at VIR was Z06 2:39.77, top speed 154 mph (with the new calibrated suspension) vs ZR1 2:37.25, top speed 170 mph.
Motorcyles aren't traction limited, but they are wheelie limited. 0 to 60 mph times have been about the same (2.5 seconds, drag strip, pro rider) since around 2000, and most of the fastest bikes redline at around 80 mph in 1st gear (1999 Hayabusa, 2018 ZX14R, 2018 BMW S1000RR). Power to weight ratios translate into a Z06 with 900 to 1000 hp, and only expert riders are significantly faster with the 1000 cc bikes versus 750 cc bikes on most road courses.

More than a few of us would be disappointed if we stomped on it and it nothing extraordinary happened 
I didn't buy a ZR for the 'snowflake" experience. Those complaining who haven't driven one or are relying on ridiculous fake news reviews need to go get a Kia and find a new Forum ...............................

Just kidding, the offer still stands.

I think the c7 sweet spot reference putting power down might be a modified, still NA GS with 550-600 hp and the more gradual torque curve of an NA engine. someone on this forum must have something like that?

What's that great line..... "What does a 'red neck' say before he dies..... Hey guys, watch this!"
That's usually preceded by the 'red neck' turning off the various traction control nannies. Note to those who think just because they can afford the Z, they can handle it... you're not nearly as good as you think you are!

When the new ZR1 was introduced every car magazine hailed it as the Corvette that destroys Super Cars. At VIR it blew the doors off the lap time. It seems like every few weeks something negative happens to ZR1. MT is right, the car makes tons of Horse Power, but it can't keep the tires on the road. Last week I tested a manual ZR1. We finally got some cooler weather in Orange County & I headed to the toll road. The entrance was a straight road which takes you to the Tollway. I was accelerating in 1st, shifted into 2nd and stepped on the throttle and all hell broke loose. The rear of the car literally jumped up & the rear moved to the right. Then it jumped all the way to the left. The ZR1 was in Sport1 and the electronics saved the car from doing a 360. Even on the toll road when in 1st, 2nd, or 3rd the tires continued to break free from the road under hard acceleration. A powerful engine with a mediocre suspension at best.
Rear tires not warmed up.
A road surface which likely has inconsistent traction due to heavy use by all kinds of vehicles, surface wear and varying degrees of "slickness" caused by lubricants leaking out of vehicles.
You were "road testing" the acceleration ability in 1st and 2nd gear of a car having an engine which generates 715-lb/ft torque and then are "surprised" that the car wheel hops and wants to go sideways?!
I suggest that you're neither very smart and nor experienced in driving rear drive cars which lots of torque. If you bought a ZR-1, you get to go to Spring Mountain for free. My advice is to go though the school before you do any more impromptu "road tests" on tollway entrances.

Would've been nice if GM made the ZR1 headlights sleeker. Just something to differentiate it from the other C7 cars.

He doesn't address the transmission differences (A8 vs PDK7) and weight differences which are pretty much responsible for just about everything he can't explain (except maybe the snap oversteer). He honestly has to be the dumbest racer ever if he can't figure out that the ZR1 brake fluid is the problem. They're the same exact brakes as the Z07 he loves. They're great on the street. The pedal collapses on the track. They're carbon ceramic so the pads/rotors aren't overheating. GEE I WONDER.
This, in a nutshell, is why you don't trust magazine reviews- good or bad.
