8 Chevrolet Corvette Stingray Z06 lap time at Willow Springs

There is a decision that needs to made about this time. Since Randy complained about how rough the Track mode setting was during the first test, GM created a new soft mode software algorithm for the dampers. This new setting is not yet avaliable on the Z06 and may be offered as an aftermarket addition. See the quote from the article:

The car hadn't been developed on a rough track, which is why Pobst complained it was too harsh at Willow Springs and was beating him up. Pobst actually preferred to run the car with the suspension in the softer Sport mode. As a result of this new testing at Spring Mountain and additional testing at Willow Springs, Chevrolet developed a new Rough Track mode for the Z06 that softens the dampers in Track mode. Chevrolet plans to make this software update to the Z06 available soon through the GM Performance Parts catalog, and our test cars at this retest were both fitted with the new software. We cannot say, then, that the improvement in lap time was due solely to the corrected rear alignment, as it's possible the new damper programming also aided the Z06's performance. "The ride was far better than the last car I drove, in Track mode," Pobst said. "It made it so much easier to drive. It was still firm. But I don't think the ride was really that important. I think it's that alignment issue because I don't get that rear steer anymore.

I think most of the improvement came from fixing the bad alignment but the car was not truely

I feel the softer suspension helped driver-confidence and not necessarily it's ability to turn, brake, and go fast.
If it had a proper alignment in the first place, then driver-confidence wouldn't have been an issue.

...Long story short, I feel the time is valid. Remember when MT first tested the SRT Viper? Same issue, bad alignment, once it was fixed, it ran MUCH quicker times.

Sure did, And most likely like the Huracan it will get a retest too, Strange things sure are happening alot with the supplied cars these days, But Also look what it has vs what it doesnt.. M Vs DCT, 300lbs lighter, Not gonna mention price. But its something to think about.

@BR2+
The 650S time was set with mis-matched tires.

The fact is that it was run with a non stock shock tune that is not available from the factory. Don't think you can call that stock

The test drive, RP nailed it on the head, ALthough he didnt get into as much detail in the first article, Really shows his experience with cars at the track, I wonder if any of us could have seen that?

On another not, 1:25.0 is a Highly impressive time, 3500Lbs+ AND a manual? And at 80k and sill beat a Nismo AND 650S? Very impressive.

I dont have a problem adding the time, MotorTrend did it with a stock car and fixed the suspension problem, SO there shouldnt be a problem.

ALthough that Yellow color im not so keen on-_-

This is a tough one for me to judge.

Most of me says "The times are valid..." while part of me says "the cars that set those times had an aftermarket suspension setup..."

I'm willing to bet that the software will be standard or optional for 2016. If that's the case, the times should stay.

It's similar to what Ford did with the free software update for their H/D trucks. The update was free at first then became standard the next year.

The alignment is not the issue. The orginal car that Randy tested was found to have the rear out of alignment so that just corrected the issue and put it back into spec. The software though is the issue. According to the article GM is only planning to offer it aftermarket (GM Performance Parts Catalog).

...If the alignment/software upgrade is officially going to all Z06's then I'd say that the new time is valid.

1:25.00-manual(1:25.76-auto) compared to the original lap 1:27.10
