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.

I got to disagree that the wing isn't slowing it down some in the 1/4 though. There are have been quite a few people remove the 1LE wing and make back to back 1/4 runs and seen up to a 2mph difference.
