there is a science to it. Not sure though if it applies here.
Back in the 70-80s one of the mags eco-ed a muscle car....maybe the duster....found that dropping the front nose really helped. maybe 2mpg
But you have to remember, there was NO slant on the front of those cars like there are today. My bet is that the slight is already in the design.
with that said, I dropped the Q45 about 1 inch in the fron and saw a slight improvement in mpg. (your'll have to search my posts)

also, smashed the IMPUL body kit becuse of the 1" drop. (again search my thraeds)

Finally, If there is ANY deterioration in the ride quality, I wouldnt do it. I had put in An aftermarket spring kit....took them off after about 5k miles. And the Q45 has electronic suspesion! I just was not going to put up with a crappy ride for the looks.
