stock? I'm a bit skeptical because the car is rated for 2.5 and the drop to 2.2 is no small feat.
Z06 owners creeping in this section with a hint of insecurity. Anytime the cars (any car) get into the hands of the public who do more testing, some of them are going to get better times that what has been reported by Car and Driver, Motor Trend, or GM. The fact that GM is stating it is the quickest Corvette ever produced, is something they are probably willing to stand behind. There is a post below saying at the proving grounds Cup2R tires were used to get 2.1 sec consistent 0-60 runs. Next are going to be owners using R888s on all 4 corners...then what 2.0? The only place the Z06 is going to be quicker is on a road course...but only 5% of less will be using their cars there.

LOL, you think R888 is stickier/faster than the Cup2R?
AWD is is a huge advantage in the 0-60 arena and yes that metric is still far and away the most advertised, quoted, and looked to performance metric.
There is already a new E-Ray owner here at this very early stage who posted a 2.1 with a Draggy.

It was for me on our roads and temps here in wisconsin. The cup 2 was really bad on cooler days. The r888r was much better in the cooler temps for me. This was at 650whp. I'm sure on the track its different.

You think GM ran their tests with cold tires? Not having a tire up to optimal temp doesn’t mean it’s slower, it just means it has a different operating range and the operator didn’t use it correctly.
For drag racing they seem to be better compared to the Cup2Rs and last a little longer. Should I put lol at the end?
The R888 came out when I got out of the Navy in ‘07, just surprised you think it’s better than the fastest tire used by multiple manufacturers to set track records. I’ll admit it may work better at colder temps, but that doesn’t mean it’s a faster tire and of course the bulb that burns brighter burns shorter. If you think they last longer, then why would they have more grip?

I guess cup r's are not a good tire for the northern states then. The toyo gives better traction at a cooler temp and all temps really from what I found. I also said on the track it would probably be different. I don't track and high speed corning isn't possible on the roads around here. I was stating my experience with both tires on the streets and everyone has there own driving needs for tires. I ran cup r tires for 2 years and toyo r888r for 3 years. The cup R were terrible for my street driving in almost all situations. I also didn't care for the run flats. I'm not telling GM what to run for tires. My opinion still stands the toyo r888r provides better street grip than the cup r. The cup R was quieter than the toyo, that would be the only positive I had. If I have issues with traction on my eray it will be getting a 888r.

The r888 from 2007 is the not same tire as the r888r.
That may be the case like the Cup2 and 2R, but he’s the one that mentioned R888 not the R and you mentioned Cup2 not 2R which are different of course. My understanding is the sidewall construction is different in the R888 and R888R, but to be clear you’re saying the compound is different right? Regardless here’s the R888R being barely faster than the P4S, slower than 220tw and the older Cup2 as well as much slower than a newer 100tw tire that’s slower than the newest 2R.

I'm refering to cup r's the ones that came on my c7 Z with z07 package and r888r's. The grip on the r888r was so much better than my stock cupR's. I actually just sold my c7z and the owner was very happy I had the r888r's on it. I really don't see many people going with the cup r and more seem to go with the r888r on the forums for street and drag strip traction. Again I don't track and can only assume the cup's need a lot of running and heat to work too much for the street. I had a 15 minute drive to the freeway and my cup R's I could easily break them loose once on the freeway at 65 while the r888r would easily stick, same road.
To be clear the C7Z07 came with Cup2s and the C8Z07 comes with 2Rs. I didn’t say the R888R doesn’t work better when cold, only that GM didn’t test the 2R when the tire was cold and say it was faster than the P4S which works better at a colder temp as it’s not designed for the racetrack where a tire gets hotter. For the street/cold tire temps the all season tire actually probably works best. The P4S had almost as much grip as the R888R, so don’t see how it would be faster than the 2R which is known to be faster than all the tires in the test. NASA actually puts the R888R in the same category as the P4S… https://form.jotform.com/83435707892164

Just for reference I also tried the Michelin pilot super sport for one year and they did not provide as good as grip as the r888r either. Although were better than the cup2.

*better when cold, not actually better as obviously the Cup2 is superior in grip than PSS was once it’s warmed up. It may be difficult to get a tire up to temp with normal driving on the street when it’s cold out. Tires made for autocross would be best for traction as they come up to temp quickly.

That's a lot typing to agree me. I said "stock?" and Cup 2Rs are not offered on the car. Still it's a pretty big drop in time for an AWD car for a change in tires. How many stingray owners are seeing .25 or .3 seconds come off their 60' from switching tires? And the stingray doesn't have the e-ray's front wheels relieving some of the car's inertia at launch so rear tires matter a lot on that car.
And no insecurity here. Some of us can appreciate both cars. I expected that an AWD Corvette would be stupid quick and got on an e-ray list in late 2020, so i'll have the option of switching if I choose. I'm enjoying the LT6 in my Z06 and rarely launch hard from a dead stop, so I doubt I'll switch.

Yeah I’m not surprised the E-Ray is quicker to 60 than Z06 either, no different in how the 911 Turbo was faster than GT2.

Just poking a little fun. I appreciate both as well. My ERay will be my 6th Vette, my C5Z appeared in Vette Mag 2X. I still have a C7Z with Maggie 2650, the way C8Z06 prices are now selling for MSRP it is awful tempting to pick one up, especially being that I'm 301 on the MacMulkin ERay list. Probably won't even get it for another year.
What's really funny is the guy in the C8 sections constantly posting that doesn't even own a C8, but knows everything because he races his older Vette.

I’m doing research for the future, is that ok with you? Obviously I know more about tires than you do, so you’re welcome for the free education. I’ve also driven a C8Z07 on the race track and laid down a time that was a second off the ACR Viper’s track record on that track, so I recommend you get one if on the fence. Had it been my car and the owner not riding shotgun I think I could have matched it if given more than the few laps he graciously allowed me to take.
