I have been saving up some old election/BP ad signs for a while for the full belly pan. I am going to have to find some way to fasten them on soon and try it out myself especially after this thread
My NX already corrugated plastic under tray that works well for cutting drag. The downside is that the motor loses some cooling...it could be an upside for hypermiling a hotter motor gets better MPG.
