Hi all - I wanted to create a thread for people to report any data about the range benefits of the aero wheels vs the 19 inch sport wheels. This would really help many of us make configuration decisions with our M3's!
I'm playing with the equation for aerodynamics for the S, X, and 3.
The "everything we know about M3" post has a reliable listing of the exterior dimensions. However the frontal cross sectional area is less than a simple length times height calculation.
I've seen a few rough guesstimates...
