ROAD & TRACK provided a technical image of the Supra after its debut.
The rear spoiler upper trailing edge is right on the AST-III contour.
As Dodge did with Viper. And Pete Brock's, All American Racing, Shelby Daytona Coupe.
Wolf H. Hucho might have mentioned that lift and drag would have been better had they just lofted the contour to that of the AST.
Reasons why they wouldn't include:
* degraded rear vision out the backlight.
* Added weight.
* Front/rear weight bias.
* A hit to polar moment of inertia.
All, something outside the wish-list for 'performance' cars.
