Gotta wonder what this car would do with Sport Cup 2s on it...Their time is around 3 seconds slower than the ZR1 redo lap from 2009 which was a 7:26.4 time. The wet Z/28 lap beat the original ZL1 time of 7:41.27, with a 7:37.4. So if the last Z/28 beat the ZL1 by 4 seconds, on a wet lap, the new Z/28 is gonna be stupid fast. Like, maybe 2012 Z06 with Z07 fast, 7:21 or so fast.
The BMW M4 GTS ran a 7:27.88 on SC2's. ZL1 has got to be faster with those I would imagine...
