On my Civic coupe that meant 4* rise from behind the rear axle to the rear bumper cover. I cannot prove it works. I just know the science says it probably does, if I executed it well enough.
I'll keep that in mind. The belly pan won't happen until late June though since my busy schedule doesn't allow me for more than a few hours of ecomodding at a time, and this is my daily driver so taking it off the road isn't practical.

So right now I'm planning on revising the wheel skirts, adding incorporated side skirts and wheel spats, maybe a trunklid extension and some gap sealing. That with as much P&G as possible should hopefully get me up to 50 MPG. We'll see.
