If you look at the data from the testing, you will see that using headlight covers actually matched the Cd of the car with the longer G-Nose. ( .467 ... eek ! ) Front end lift was minimized, but less air made its way under the hood of the car.

I'm not sure if this is too accurate, since they used several cars, and some had flares and such.

While looking at the cars involved in the test, it appears as if the car that had the G-nose, as well as the car tested right afterwards with the headlight covers both lacked flares - so the test should be relatively similar ..... except that looking at on test # 19, a stock 240Z has a better Cd that either ( .454) and of all things, when test with wheel flares the Cd went down ???

Hmmm. I wish they had stuck with just one car.

BTW
I had one of these cars. It was like driving a parachute. Let off the gas and it was like having an air-brake activated.
