Traction Control???
1. They leave the ABS always on
2. In order for the ABS to work properly they have to leave the traction control on to "monitor" road condition but " unobtrusively" (according to them)
3."Unobtrusive" means not intervening with driver input "except" where said intervention is to facilitate the proper operation of the ABS
All that with a little smirk on their faces and when pressed they always admit its the company "brass" that has the final say on "safety" ( you have to admit this was brilliant)
Lawsuits on Euro car companies are almost non existent and on US car companies are prevalent ..So answer this do you think the CEOs at GM are going to leave themselves in actionable legal positions by not doing what their counterparts do and exposing their customers to harm or partake in the same "ruse" of "Unobtrusive" TC and full ABS ?
I don't agree with the "ruse" but fully understand it ...This is how I came to my LOGICAL conclusion
GM isn't Ferrari. They actually have a brain when they design their cars. ABS is monitored through wheel speed sensors, mounted in the hubs. This sends signals back to the ABS controller, which also monitors fluid pressures, and pedal input. The ABS controller then pulsates the brake activation accordingly so that the wheel will be able to maintain traction while continuing to make steering input in the wheel during an emergency, or deep braking situation. It has nothing NOTHING to do with the TCS system. TCS sensors are mounted in the diff IIRC. I know for a fact that they aren't the same sensors that are used in the ABS. And never have been since it's introduction to pretty much any GM performance car.
If you mean the ELSD that's another kettle of fish. And Gm still does THAT differently to everyone else. Rather than working through brake side bias, and the TCS system like everyone else, it controls the actual state of lock or open ratio of the Diff.
If you want to go full on ***** out, you can.

GM's been putting TCS on the Corvettes (and F-bodies, and other performance cars) since the very early 90s, if not even earlier. Historically, TCS has just had a simple "On" and "Off" setting. In the "Off" setting: it was really and truly off. If you wanted to light the rear tires up or wipe out, you could do it with ease.
During the mid-90s, GM developed their Stabilitrak system. On the Corvette it was called "Active Handling", but it was the same system as used on their other cars. It didn't appear on the Corvette until mid-MY '98. It had 3 modes: On, Comp Mode, and Off. Like the TCS before it: when set to "Off" it was: Off! If you wanted to spin the car, it would stay out of the way and let you.
Trust me: I know this from first hand experience!
C6's Stabilitrak was better polished to include an extra mode, but it still includes an "Off". The PTM on the C6 ZR1 and later C6s also has an "Off" setting that will let you put the car right into the weeds if you want to.
C7's system is no different, it's just full of more polish and more inputs (wheel temps, for instance). But if you want it turned off, you can do it.
The other vociferous participant in this thread isn't speaking from a position of experience with Corvettes or any other GM performance vehicle. If he were, he'd know full well that what he's writing isn't true. Neither of us are presenting opinions (though I did accidentally say he was "opining away"). We're presenting facts. It's just that one of us knows a bunch of facts that aren't true.

The Best of Corvette for Corvette Enthusiasts
I get on a track.
But, on the road - it isn't your place to pretend you are a professional driver. The safety features keep you alive and prevent you from killing a family.
A little trick I learned was to turn off the TCS after the first 10 feet or so (while the tires hook-up).
It's easy to do as the On/Off button is on the front of the steering wheel and I can hit it with my left thumb while keeping both hands on the wheel.
It makes for a smokey 50 yards or so with pretty good control.
