I know it's been 2 years but I was thinking about aerodynamics and minis the other day as I passed a truck on the freeway, trucks have turning vanes on thier sides particularly where the radius of the curve is too tight for airflow to remain attached otherwise. The vanes force the air to follow the body and therefore reduce reversion and drag. I also read something about turning vanes being used in inlet tracts...
Anyway much of the aero problems the mini has seemed to be cause the air was being asked to make too tight a turn.
I found this article using turning vanes to improve the aerodynamics of a landrover discovery.
