The JDM panels only add about 2.5lbs. Trans tunnel covers about 4lbs but in a major drag area. Also spread evenly across the lowest point of car.
I dont have the numbers off the top of my head but just from those I think the added weight breaks even from drag reduction at 25mph and then is essentially equavalent to 100lbs weight reduction at 100mph.

If that's true, that's good enough for me. Any links to the assessments to back it up?
