There is an easy explanation for this... Stock z06's can trap 125ish. So the z06 u raced should trap 125+. A car thats well over a second faster and easily traps 10-12 more mph than us should *** rape us. Why that didnt happen. I do not know. Stock ls3 vettes are 11 second cars and like all vettes are hwy princesses. The outcome of that race seems about right. Can ur buddy with the Z06 drive it well?
