I watched a blown Cobra run a z06 at the track Saturday. Now, the vette was on slicks, and the Cobra on street tires. But I know the snake was modded a little, and I don't recall the z06.
Both cars are darn fast, but the Cobra had traction issues. So he lost to the vette, but on even tires, I'm not sure what the result would have been.
Seems like it really would come down to driver ability.
