BBsGarage,
Pretty slick looking. Is that flashing or mudflap or something else?
You got me thinking... if I use flashing, I can angle the exposed portion back toward the wheel.

Okay, after a long absence from modding, I've done a couple of items. First, I did change the upper grill block from duct tape to sheet metal. No big deal there, just smoother and a little better looking. Although I do think I may have to get a ecomodder decal to put in place of the Toyota badge. The other thing I did, just today, is attached a crude, two-piece, belly pan, attached with four zip-ties each.

It only goes back about a third of the way, just past the front wheel well. Thoughts?

First day results were great. On my typical commute home, I'll get around 47mpg. This time, 49.4! The first 90 miles are showing 47.5mpg.

rear spoiler

But I'm wondering, am I missing something?
Looking at your car from this view leads me to believe that a rear spoiler would help at highway speed.------------- If you can find a flat level spot to park the car,lay a straight edge across from your trunklid to the top of the car.------------------ If the angle,as measured from the horizon,is any steeper than say 13-degrees max.,then you probably have separated flow behind your roof which is not re-attaching ( like a Lancer).--------------- A simple bent sheetmetal spoiler,angled up no steeper than 30-degrees,and tall enough such that it just intersects,say a 12-13-degree line coming down off your roof,should get you flow re=attachment and lower drag.------------------------- Better to compare it to the streamlining template,as this would give you a more accurate appraisal.See Project" permanent Kammback for Metro" or "Aerodynamic Streamlining Template".

Huh. Would never have guessed a spoiler would help. I'll look into it!

Just had my best tank at 46.6. The belly pan rocks!
