I have these on my Optima Hybrid for over 3 years now, they are quite good on this car and have even performed well in snow. They do have a bit of road noise which can be expected of performance tires, but that does not detract from the performance. I am able to spin them if I apply enough acceleration when turning from a stop. The hybrid has @275 lb ft of torque, the wider tires on the Stinger should be fine with them. The tire I had last on my Stinger was the BFG g-force Comp-2 AS, which were really great performers. Seems they came out with a Plus version that no longer has a tire for the rear, unless you are running a non factory setup. The choices seem low these days for the stock tires on the GT2 on tirerack.
Depending on your use, I think those will be fine. They come in 4th overall on TR tests.
