That's extra weight right there, people spent $1000 to shave 1lb off their car with Carbon Fiber and fancy wheels .....
You guys need to lay off the whole benchracing thing. If you have a chance to drive both, you will know the difference. The Corvette is an extremely difficult car to drive. I owned a non Z06, but I have driven many Z06s and I can tell you they really put the scare in you at the track or even in a parking lot. Heck, I am afraid to drive it on the street. When you spin in a fast car, you hit things a lot harder as you slide a lot more.
