Do you have any pictures of the front belly pan? I'm planning of doing the same thing on my Impreza, but the front underside isn't all flat.


Thanks Gil.

If the stock airdam is extend lower than the body and suspensionn then adding size may only add frontal area aka pushing more air.
my theorem

my theorem
At least 4-investigators measured drag increases when the depth of the air dam was increased beyond some optimum depth.
For racing,1-investigator found that a 'VERY' low air dam would give a 1% drag reduction,although it would be useless for the street.
An 'active' air dam could address this issue.Volvo's done it.Ford has done it.
