sorry about the inaccuracy...11.4@127 is indeed what GM publishes. At near 0ft DA my '17 ZL1 trapped 129.1. No dyno #s unfortunately. Aero drag wasn't really any hindrance running the 1/4 mile. Seems like on the road course above 130mph I can feel more drag in the ZLE but no data to back up this "feeling". It certainly didn't feel like it was dragging an anchor for the second 1/8 mile. If a ZLE were running the 1/2 mile likely the numbers would suffer compared to a standard more slippery ZL1.
