I found this... 28" wide is pretty cool and the price is kinda in that range of it's going to take a long time to pay off in fuel savings (especially considering I'm really only guessing that an airdam will help) but at about $30 for the pair I'd need..... eh, not bad. I've spent more than that on stuff that does me no good at all (like tequila)

Not entirely sure how I'll go about attaching it... the idea is to go somewhat below the lowest part of my chassis so I have to mount it low. Think I'll keep looking a little longer...
