Now that I've ordered some coroplast (finally found some from a sign shop, had to pay $13 per sheet, though), I'm going to be smoothing out the front underside and deleting the horizontal stock air dam under the radiator, similar to this mod:

I'm going to be leaving a little lip sticking out the front, though, to act as a small splitter. I'm going for both drag and lift reduction! XD
You can see the stock flap sticking down in this pic:

I'll also be covering the gigantic opening on the rear with a sheet, because you can see here how aerodynamically dirty that is:

I'll also be using the scraps to close the rear wheelwells, and get the front tires out of the airstream. Currently, I have tire spats on all 4 corners, with the front ones made from the excess of the rears after I trimmed them down:
Front:

Rear:

I already have a lip spoiler and vortex generators, but I need to get some more of the adhesive and move the VGs back a bit, since at their current position I'm getting rather large counter-rotating vorticies. Apparently very good for lift reduction, but I'd like a little bit of drag reduction as well.

The material should be here Friday, so over the weekend when I'm not studying for final exams, I'll be under the car cutting, drilling, and smoothing.

Oh, is 4-mil coroplast thick enough?
