Let us know what you hear back. I have the Continentals as well, and while I like the overall performance, the drivetrain does appear to have a little too much torque, which results in a little bit of slip if I have to punch it on a wet surface. (doesn't happen often, but it feels super sketchy when it does)I have the Continental LX Sport tires on mine and hate them. Not good wet performance, car slides to much on curves. I am talking with my dealer now, they are seeing if I can get them replaced with something different. Waiting to hear from GM.
