[Sulfuric]

But my back windshield has a steeper angle than a 2006 Corolla, so vortex generators should have a positive effect.

EDIT: I think I'll forget the VG. Not enough positive evidence for small cars for me to try them.

My next mod will probably be front wheel skirts, but not until i get back from xmas break on Jan.2, and even then, I doubt they will be finished until around the Superbowl. I'm lucky enough to go to the Sundance Film Festival, so that cuts me short about a week too.
