66 or 67 Dodge Charger never was supposed to have a wing. I have seen this car in person and it is very nice and the wing compliments it.[/QUOTE
I just found this out. I better keep mine below 150 since I don't have a spoiler

"In 1966 Dodge took the Charger into NASCAR in hopes that the fastback would make their car a winner on the high-banks. But the car proved to have rear end lift around corners which made it very slippery on the faster tracks. The lift was because the air actually traveled faster over the top of the car than under it, causing the car to act like a giant airplane wing. Drivers would later claim that "it was like driving on ice." In order to solve this problem Dodge installed in a small lip spoiler on the trunk lid which improved traction at speeds above 150 mph (240 km/h). They also had to make it a dealer-installed option in late 1966 and through 1967 because of NASCAR rules (with small quarter panel extensions in 1967). The 1966 Charger was the first US production vehicle to have a spoiler. David Pearson, driving a #6 Cotten Owens-prepared Charger, went on to win the NASCAR Grand National championship in 1966 with 14 first-place finishes."
