the Z06's light weight advantage is minimal once the M6s weight and momentum is already moving forward.
Wrong. It's the SAME. The only thing that changes throughout any acceleration curve with mass and power being equal are the drag forces based on the velocity of the air. The coefficient of drag has a HUGE influence on the speed of an automobile--especially as speeds increase. So I am sorry to burst your bubble about the rolling start having an advantage to the M6 based on weight. On the other hand, gearing would also influence the start at X speed. The lower velocity of the start while still reducing the chance for the tires to break free and the lessened likelihood of false starts, the better and likely more fair for all of us.
You can paper-race all you want. Numbers posted on paper are variable with altitude and temperature. I raced the Z06 twice. You can speculate about whatever you want, but we all have the video to watch.
