sacremon;
Nothing that you would ever notice on the streets. Now if you were running a 500 mile race with 40 other vehicles that are almost identical to yours and you had the deflector on a nd the rest did'nt then I would worry about the drag Co. Lowering the vehicle, adding a spoiler or effect kit, air deflector, or exhaust change the drag that the vehicle will have. The difference is that the average joe on the street will NEVER no it. I'm not attacking you or anything of the sorts, I just found that to be a bit foolish.
