The feel of how this car handles corners with different road surfaces is delightful. I have had to privilege of driving almost all performance oriented Chevrolets including the new C7 Stingray at the track in Las Vegas, spring mountain motorsports.
Based off of seat time, and no actual times or competitive comparison. I familiarize the feel of this Unit to be similar to a bone stock C6 Corvette, only less twitchy and much, much more forgiving... Turn in is nearly identical, only thing your missing is the back end coming around wildly. The SS requires you to actually "try" to kick it out (in dry weather) which I look to the weight, weight distribution and suspension to pay homage to for this major improvement. I'm no pro diver this is just based off the seat time I have been privileged enough to experience.
At the end of the day this creature handles in a way that I have never experienced, extremely flat and balanced in high speed turns. looking foreword to getting used to this new personality in my driveway.
The SS feels nothing like the G8 imo, never really "drove" a gxp though. G8 felt very fat and just plain dated. However the Lineage is absolutely undeniable. if you have a G8, the SS is your father.
