Found an Aspire forum where a member took some inspiration from Ecomodder members (FastPlastic, Daox, and someone with a black T100 regular cab) and made himself an air dam.
Ford Aspire Com - The Internet's #1 Ford Aspire and Kia Avella Resource! -> Coroplast front bumper project
Here's a pic of the guy's quick mock-up for reference:
I'll be doing the same kind of air dam, but I'll probably close the upper grille and cut some holes in to let air into the lower grille. I'll also put in something to force the incoming air through the radiator like I did on the Tempo. I've noticed the Aspire's temp gauge likes to hang around the middle.
