2nd gear on highway, going low 60s MPH ~4,000 RPM. Car broke traction and went sideways before traction control kicked in. I was in Touring mode.
I bought the Z06 because I figured when would they make a rear wheel drive car in a manual with 650hp again? I am a big believer of not driving like an idiot on public roads, but I’ll accelerate on an on-ramp or maybe power oversteer a bit into a turn if nobody is around/nothing is nearby.
You can control the acceleration if you modulate the throttle but this car breaks traction at will. I cannot imagine how it is on a track? Can you hammer the accelerator coming out of a turn?

Based on your description you were operating at part throttle at 4000 rpm and dumped the throttle. 4000 rpm is only 400 rpm over the peak torque point of the engine. You went from some small amount of torque at part throttle to close to 600 lb ft of torque almost instantly. With that being geared down by being in 2nd gear on a cool day there wasn't a tire in the world that wasn't going to break loose under those conditions. The shock load on the tires was just too high. It wasn't the high horsepower that got you it was the high torque. Yeah, HP was up around 500 HP at that rpm but the torque is what hits the tires.
On the track, with both PSS ZPs and Pirelli Slicks with the car in 2nd gear I can roll onto the throttle coming out of Oak Tree corner at VIR and be wide open before the car reaches the track out point. It helps if you have the car in Track Mode Sport 1, Track Mode Sport 2, or Track Mode Race. Those modes activate PTM which modulates the power to the rear wheel that has traction and limits power delivery to the traction available. Basically, go past the apex and nail the throttle. However, though it is theoretically possible for the system to behave this way on all turns there are some that I can't go wide open without the back end stepping out. Read your OM on how to drive the car on the track using PTM.
What was the ambient and tire temperatures like? If the road and tires were cold (like below 40-50 degrees), Weather mode would have been more appropriate. As far as the track, as long as the tires are full warmed up but not overheated and the surface has good traction you will have good traction on corner exit.

good question - sorry I didn’t include that. 45-50 degrees, I had been driving for at least an hour beforehand. But I think they’d be considered “below” ideal temp. I have a Carbon 65 edition without Z07 so I don’t have Cup 2s.
Yep, I'd say the ambient temperature was a factor; I've found the MPSS to be relatively greasy in the 40's versus what you'd expect in the 90's. Additional potential factor is if there was a crown on the road. Third, also have to consider there's a lot of power on tip in from a hit at 4,000rpm. The one hour highway drive certainly put some temperature in but it's not near the temperatures you'll see after a warm-up lap.
read your owners manual,SUMMER TIRES ONLY,not safe under 50 degrees.these cars are killers of inexperanced people.learn to drive in warm weather and make sure your wheels are straight before you punch it because they like to kick out left even with TC on.

GM's documentation says nothing about 50°, everything they have posted has been related to 40° or under. I have driven my Z06 at 700rwhp more times than I can possibly count into the 20's, 30's and 40's. Zero issues as long as you drive the Z06 with respect. Top it off I drive in Sport all the time, never once have I used any of the weather modes on my Z06 nor on my previous car which was a 650rwhp 17 Camaro SS. Neither car has even done anything that I didnt expect.

definitely true. They are summer tires. It was fluctuating between 45-55 all day but yes that was a risk.

congrats on the new car. It is a beast. NEVER turn off the Nannies on the street.
I took the spring mountain class for the z06 so that i learn about the car at high speed. I suggest taking it easy and only mash it on an empty road, no ditches, poles, or walls.
I would start off by buying some adjustable toe links for the rear and get an alignment. The factory alignment GM calls for is for going around a race track. Makes the car very twitchy on a street when the tires spin. You may get away with not needing them if the car isn’t lowered on stock bolts.

Congrats on your new Z! These cars demand respect especially with PSSs in colder temps. They never heat up when temps are below 60. I would suggest a second set of wheels with all season tires like AS3+ or the new AS4s. I run AS3+ on ZR1 wheels from October through April. Then I can drive my beast all year long road conditions permitting.

Thank you! That is terrific context for what happened. I drove the car all day today in around 50 degree temperature. As long as you are careful with the throttle it drives like a “normal” car. Any additional throttle (intentional, especially off the line from a stop) and you can easily break traction. Definitely an interesting car! I traded my ‘66 427/425 L72 coupe for this car. Very different experience.
I was going to ask the same thing for I too being a first time Corvette owner which is also a Z06 I’ve noticed that it’s real easy to spin the tires from a low speed to fully smashed pedal. I’m in Florida so the temps are at least above 60 deg right now so I’m chalking it up to learning how to effectively control and manage the power this thing has. That will come with more seat time.

The 2015 Chevrolet Corvette Z06 comes in certain forms comes with high performance Michelin Pilot Super Sport Cup 2 tires that are intended strictly for summer use,

Driving with competition oriented tires on snow, ice, or cold road surfaces can cause loss of control or an accident. Competition oriented tires are summer season tires and are not intended to be driven on snow, ice, or road surfaces below 10°C (50°F). Do not drive a vehicle with competition oriented tires in these conditions
