Why is the original car's aerodynamics so terrible to begin with? Some thoughts...

- High off the ground . It's as high (or higher, depending on the source) as my hatchback Flea!

- The bodywork around the rear wheel arch is terrible. The wheel sticks out dramatically - looks like the edge of the tire is exposed for as much as as 2/3 of its height. Which means any attempt to boat-tail the bodywork after that point is a wasted effort since the air is already disturbed (and further churned up by the chunky alloys).

- the wheel arches are also pretty large, with a big gap between the tire & bodywork.
