Investigation of the aerodynamics of the toaster-shaped Mitsubishi Colt Ralliart Z27AG using basic wool tuft analysis and other techniques.

This episode: I revisit Sandown Raceway after 5 years better prepared to try and determine if vortex generators are really worth it (or not) on the Colt as a drag reduction device.

rcoltlyf is not a trained aerodynamicist, mechanic or indeed anything to do with cars. He is a scientist though, likes understanding how things work, and really likes his Colt.
