If the Z/28 is 3 seconds faster than ZL1 on a 2.9 mile course, the
theoretically it would be about 4 seconds faster on VIR, a 4.1 mile course. of course this doesnt take into account the course differences themselves, so that could be an inaccurate number.
but, 3-4 seconds faster than the ZL1's 2:57.5 on VIR (
C&D's Lightning Lap) means this car
might be running with the c6 z06, porsche GT3 RS, GTR, etc...
