Not as the GCR defines it:
Aerodynamic Device - An attachment to, or an integral part of, a car intended to generate atmospheric downforce by the action of air flowing through or around the attachment.
I, for one, think the Stohr is perfectly legal. This is not significantly different than an RT-5 with tunnel skirts and the footer plate just ahead of the rear tyres - the later Pro cars were just late to the party by about 10 or 15 years! Besides - the way the rules are written, one must argue intent - and with the big honking rear tyres mandated by FA, I should think that the real intent is drag reduction!
