[QUOTE=Tango Charlie;72058]Dittos on all the congrats. It looks great!



That nice smooth taper aft of the wheel is producing some sideways lift, eh? (trying to speak your language, eh? )
Lift does produce drag. It would be an infinitesimal improvement, but I wonder if you could eliminate the production of lift without increasing drag? This got me thinking about lift produced elsewhere on cars, but maybe that should be discussed elsewhere...

Those trailing edges are lifting because the air on the outside is moving faster than the air on the inside, but there are such pressure variations all over streamlined cars. They cant' be avoided, but they can be harmonized to avoid turbulent drag.
"Lift creates drag" refers to induced drag from leaving the wake moving in one direction, while these forces are averaged out from each side.
