would a bigger airdam help?
Hucho warns that a deeper airdam can increase drag.Extremely low dams can cut drag,but without being 'active' they're torn off on the first driveway ramp.
Brett Herndon,of Aerolid fame,constructed an absolutely fabulous airdam for his F-150,but was forced to modify it,as it's extended depth cut into fuel economy,just as predicted by Hucho.Active aerodynamics is the solution,but adds a couple orders magnitude to build complication.
