Difflow Diffusers - Lotus Elise and Exige Flat Track Diffuser Is more for providing aditional downforce on the rear wheels for handling. It also helps direct the air from under the car to the low pressure area behind the car in a more smooth fashion so you get the downforce with not as much turbulent drag as not directing the air. At least in theory. It's documented in race car aerodynamics books. For street speeds, the boat tail or Kamback will reduce drag more for better fuel economy. Depends on the intended use when finished with the swap. The ex-wifes 1990 Corrado had a tail spoiler that moved up and did help keep the rear planted in excess of 100mph. No clue if it help fuel economy at those speeds.
for a rear wheel drive VR6 swap the easy way
I saw this truck at Southern Worthersee a year or 2 ago.
