You gotta remember that the real-life counterparts to many of the GT5P cars have fancy-shmancy traction control, anti-lock brakes, and stability control that are all tuned to the very specific setup of the production model. (Chevrolet calls it "Active Handling System" on the 'vette)
GT's traction, anti-lock, and stability systems are all generic and fairly esoteric by being reduced to just a number setting, and many people play with all of them turned off.
Drive a Z06 in real life with Active Handling on, and with it off and you'll encounter 2 very different beasts. The real question is: Does GT5P's Z06 with all assists off behave just like the real-life Z06 with all of its fancy computer assists off? Any other setup and you're looking at the difference between a very specific assist in real-life versus a generic assist in-game.
