[EcoCivic]

I was thinking about making a belly pan for my 05 Civic to reduce aerodynamic drag. Then I read on this forum that I can get 75% of the aerodynamic benefit of a belly pan just by making a front air dam. If that is true, I would much rather save the time, money, effort and weight and just make a front air dam. How much of a difference does a front air dam make? I am considering making one, but I am not really a fan of the look. I would be OK with it though if I could gain at least 0.5 MPG on the highway. Is a gain of 0.5 MPG or more likely to happen? Thanks for the help, I am new to Ecomodder.
