The 2000 and earlier C5s had TC that was very suppressive. It would trigger pulling out of a parking lot if there was a slight bump where the road surface met the parking lot surface and the car was turning left or right. Post 2000 C5s had a less intrusive TC so worked differently. The C7 TC is more forgiving than the late C5 TC and lets the driver spin the wheels more before taking action. Remember that all C5s and C7s have limited slip diffs. That means both rear wheels are more likely to spin with sudden applications of power. Most vehicles on the road have open diffs where only one wheel spins with added power leaving one wheel with lateral grip which restricts sideways movement. Since most drivers have very limited experience driving with LSDs they don't know how to react when both rear wheels start spinning and all rear lateral grip vanishes. When that happens the rear of the car will move in whatever direction gravity pulls it. If the road is sloped to the right the rear will move right and if it is sloped to the left the rear will move left. Other factors can change that equation to some degree but in general, gravity overcomes them depending on the slope of the surface. The easiest way to find out how things work is to find an empty parking lot during a snowstorm and practice getting the car to move when grip is limited and speeds don't exceed 5 or 10 mph.

OK...... the C7 "stability control" switch is located where?

 

The C7 is a wow factor! 👍

I doubt that the track devotees are much better. They're gonna have to prove it to believe it.

 

In 2013, actor Paul Walker died in an accident in a Porsche Carrera GT. An investigation determined that the Porsche was driving on 9-year-old tires and traveling at speeds between 80 and 93 mph when the driver, Roger Rodas, lost control and collided with a power pole and several trees. Rodas was also killed.

Traction and stability control can only do so much. One technique that can help is, when it gets crazy, do not come all the way off the gas. Come off to about 50%. Why? As you come off the gas the car's weight shifts forward. Just when you need rear traction, you gain front traction and loose rear traction. One way to gain experience is find a road where there is no traffic and preferrably no houses. A large parking lot is usually hard to find but even better if available. Use first gear, no need to dump the clutch. Get up to maybe 2000 in 1st and nail it. See what happens. Get used to it, and get used to how to get out of it by reducing gas. Now go to track mode and hold down the center of the **** until one of the lights comes on, keep holding until the second light comes. Now you have no traction or stability. I say do both just to confirm which light comes on first, meaning which system is off. Try your 2000 nailing it to see how the systems change how the car reacts. Now, if you really want to learn your Corvette, start running autocrosses. With a base car like mine run them in Track w/ both systems off. If your car has mag ride, try the different modes because I understand that some modes can actually be too stiff.

 

We have a 2017 Z51 A8 and two sets of wheels/tires: stock PSS for summer and AS for winter.
Our Owner Manual recommends replacing the tires when they are 6 years old, regardless of remaining tread.
When both sets got to the 6 year point, they both had about 4/32" tread remaining, with even wear. But I replaced them anyway, and the improvement in traction was considerable all around- accelerating, braking, and cornering. My personal experience is that new tires will make a big difference, and my tires were only 6 years old instead of 10.

 

Won't help you under WOT. Doesn't matter what your tread depth is. You missed the point.

 

This is why C7 and earlier is more desirable to me than the C8. The C8 gave me no sense that it’s really to put me sideways in the blink of an eye and potentially kill me.

If you do the same thing the OP described, I’ve noticed the standard traction/stability control will let the car go a little code brown before it saves you. To the point of I just don’t know if I trust it. That rear end starts snapping sideways…that’s an awful lot of yaw inertia to try and correct with brake intervention. If you have Z51/Z06/ZR1, and you punch it in the first couple steps of PTM, it pulls the power before any drama happens.

 

If changing out 10 year old tires won't make a difference, then all racing sports would just keep the same tires. Maybe better said, new tires will help but he can still put himself in a ditch if he's not careful

 

I'm glad to read this thread because I was thinking my traction control, etc. had been "tuned out" somehow. Mine has 650 HP and I have never felt the traction control work. I've seen the light come on, but felt nothing.

 

@ WOT, it won't much matter about his tires....

 

Join the club. The mighty C7 takes no prisoners.😉👍

 

really ... again .... ??? Only 460 HP at wide open throttle and you think it's uncontrollable with good tires? lol lol what you need is what's known as the "Driver Mod" lol lol

 

You are talking about a completely different scenario .......

The OP has a stock 460 HP car with 7 year old all seasons tires You , with 650 HP and I am assuming sticky summer tires or drag radials, will quickly get to the point where physics takes over .... your power out runs your grip .

The light comes on , the system is doing all it can to control the car .....

Do you want a fun ride ? Turn it off , you will find out real fast how much stability and traction control are doing to keep your car heading in the right direction

Really.....

Who's saying tires control your car at WOT?

 

But you said that "tires control physics," in your last post?@ :

 

In times like this, the "Ignore" list is your friend.

 

I didn't say I was pushing it to it's limits. I mean I feel nothing at medium acceleration. Yes, I have pretty new tires and I'm surprised at how easy it is to spin the tires. I have felt pedal feedback in an older Camaro. I don't feel nor hear anything happening in my car. So, again, I'm not referring to I'm at WOT and wonder why nothing is happening. I'm at medium throttle, just goosing it and I feel nothing.
I will try turning everything off for comparison.

 

Nah, I love the Skid man. He knows nothing about everything. So when he “spits knowledge”, I listen

 

The new rubber goes on Wednesday. I'll report back what it feels like with fresher tires.
