The official number for the C7 is 12 sec in the quarter. This is a really quick time... .3 in the quarter is kind of a big deal. I know guys who spend lots of money to shave that off their times.
It is impressive. But in pure straight line such as this, the non-Z51 is slightly lighter than the Z51 all else being equal and should turn a better time by a hair IMO.
