Thaty rear hatch kit looks good. The wide body that is shown on that car won't add much to frontal area, but the door section needs to be smoothed out, so that may also work for you.

Couple that with low offset front wheels, and you may have a good combo for front wheel skirts.

If you install that hatchand add ducts, build them using louvres, so theY actually do something at speed. The ones illustrated will only disrupt flow in those areas. It's actually best to vent the engine bay directly behind the car, just below the tail of the decklid, so it fills the wake void behind the car.
