Investigation of the aerodynamics of the toaster-shaped Mitsubishi Colt Ralliart Z27AG using basic wool tuft analysis and other techniques.
This episode: I borrow some Ferrari aero tricks try to make the best possible front wheel wind deflectors based on the science to reduce drag on the Colt. Mistakes were made but we got there. It is long and just a little bit ASMR.

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.
