I guess it doesn't matter, but is yours AWD or no?
I broke the rear loose on my first test drive of an AWD GT2 a year ago, on back-road I am intimately familiar with. The sales guy was visibly "quite surprised" but after a few more curves, relaxed a little.
I'm not bragging, but I do have track and race-school experience, and have 30-yr experience driving (and sometimes owning) performance vehicles. You can push any combination of options past their limits (I've done it in an R8 and LP560-4 on a race track) and the Stinger is no exception. Be careful, however, because it takes a LOT to get past those limits, and once you do, with this much weight, you'd better know how to reel it back in without even thinking.
This is why so many "average" wrecks these days are so severe. Modern cars are fabulous at maintaining traction and control, right until they don't, and then the average driver has no chance of recovering. I had one right outside my house this afternoon, slight curve, a little rain, in a Civic or similar. Just a little too fast, most here would quickly feel the change in steering and correct, most *not here* have no clue - resulted in a backwards curb jump into a tree, and a ride in an ambulance.
Think about how much better the Stinger is. Think about how much worse it will be when you go past those limits.
