At the bottom of the article he states,

"The end result was a great increase in performance at the expense of increased fuel consumption."

this being said you would also see improved fuel mileage if you drive conservatively. That is the whole idea behind this article.

I would also buy lightweight aftermarket wheels to help decrease total weight. Maybe a space saver tire or even no tire unless you are planning a long trip, and keep the clutter out of your car.

Avoid jackrabbit starts when you leave an intersection etc.
