Wind tunnel testing Confirms the 
aerodynamic advantage of our mirror housing
shape and the Extreme Aero Extension.















Drag vs MPH numbers
(raw wind tunnel data):








Shown in the airflow simulations below - the effect of the Extreme AERO extension: 
The first photo shows the turbulent air in the wake region (behind the mirror) without the AERO extension.
The second photo shows the smoothed airflow from the AERO extension resulting in a drag reduction of more than 25%.
(You'll notice from the drag vs mph graph above that just the basic shape of the professional mirror is about 20% less drag than a standard racing mirror
and adding the AERO extension reduces the drag by almost 50% from a typical racing mirror)
