The ZLE has some impressive downforce, so much so it hurts top end speed as has been posted above. A few years ago I took my bone stock C7 Grand
sport to the 3 mile runway at Kennedy space center. From a dead stop to the 2.7 mile trap I did 180 MPH. Later a guy brought his ZLE with 190 more HP and did 178 MPH
