Exclamation Show me your wheel spats!!!...

I'm in the process of researching how big I should make my wheels spats and where to place them. As I've been driving, I've been looking at cars driving by and seeing who has what. And surprise, surprise, 99.9% of them are NOT American vehicles. Imagine that... Anyway, I see some that face straight down, some that are angled forward a little, and some that are angled back towards the wheels some. I even see some that are mounted 4-5" before the wheel wells (mainly on BMW), while most are flush with the wheel well liner itself.

So post up some pics of your front and rear spats, whether they be stock or home brewed!

Many thanks in advance!

I take it those are DIY spats? Notice any improvements?

And I sure hope more people contribute to this thread.

i have dual frontal dams, where the original dam follows the wheel well liner and curves back, (it doesn't curves up on the right side, just back, but the angle of the picure makes it look that way) this is made from thin coroplast, and it's not really strong enough, as it fonlds back at high speeds. i know this as a tiny bit is grinde away by the tire after a long highway trip. i'm not sure if this is entirely bad however as in that position it will seal of the front of the wheelwell and the gap between the tire and the front bumper



in front of this dam i build a new dam at approx 45 degrees angled out. this dam is also larger in front of the tire



my inspiration for this is this:

i'm not sure if it's perfect or if flat wouldn't be better, but so far my fe don't seem to suffer and the car feels lovely stable at highway speeds.

these are my rear dams, made them small and as an experiment, buy gluing two plastic L brackets to the underbody and taping coroplast to it. they seem to help as my average FE is pretty good since these where on



finally i have rear strakes behind the rear tires, simple L bracket that are screwed to the bumper... inspired by the previous prius.



finally i have an undertray covering the entire area in front of my tires, and i'm looking to extend this to cover the engine bay.

i also have my front grill almost completely blanked off from behind

...unfortunately, I have no way of posting any pictures, but take a look at the front wheel spats used on the 2009 and 2010 Pontiac Vibes.

...should be similar devices on the 2009 and 2010 Toyota Matrix (and Carolla's).

I just installed prototypes made of coroplast and duct tape, modeled on this pic posted by Old Tele man:

Black and Green will be rebuilt over decades as parts die--until it becomes a different car. Goal is only 60-70 mpg at posted speeds. I'm not trying for highest possible mileage.

If I were to do it again, I might move the front wheel spat in by about 2 inches.
