I have a 2002 2 door echo sedan, i have done a partial grill block and am going to do rear wheel skirts and belly pan, i saw wind tunnel pictures for a hatch and a sedan , the sedan had less than half the turbulance/drag at the rear of the car, how much benifit is in aero modding my echo rear, and what shape ,,,like the aero civic? the ford fusion hydrogen 999 speed record car has a funny car style rearwing on it. does that work cause it looks alot better than a boat tail.
