Has anybody cut out holes in the rear 'skirt' and put in some metal mesh to make the underbody air flow through it instead of gathering behind it? It might make a minor improvement in wind resistance.

(If you don't know what I mean, I'm talking about the very lowest 2 pieces at the back of the box. The right one is notched for the muffler.)

 

thats a new one but sounds like it could look sweet if done niceley not riceley

 

Here's the basic idea. The hole shape is obviously up to you.

 

I'm going to be getting a new lip kit soon, and I'm considering actually making a rear belly-pan to accomplish the same thing.

That, or just cutting out most of the center section of the rear lip.

I agree with Nastos, though-- put some thought into it, and your idea should turn out ok.

 

Looks like rockets should be coming out of there.

 

I don't think it would make a difference at all. It's more likely to look really bad too.

 

i agree with him^

 

I don't know if it'll actually help air flow, but as far as visuals go, seems like someone with basic photoshop skills could do a quick rendering to see what it'd look like....

 

yeah might look cool but doubt will have much noticable gain since xb is only like 108 hp to start with not to mention the front sits lower than the back so not much resistance is hitting that back lip.. i would like to see a finished product... but doubt it would improve quartermile times or 0-60

 

playin in photoshop on a boring day

 

not a big fan of the mini truck look on the xb but thats a sweet concept

 

homer: what are those?
car saleman: they are speed holes, they make the car go faster.
homer: oh right...speed holes...

 

Ned: Whatcha diddely-doin', neighbor?
Homer: Aw, putting speed holes in my car. Makes it go faster.

LOL

theres one already pre fabbed

 

^That'll work

 

for some reason i hate the look of the x1 kit installed. makes the car look like its stance is way too high

 

ricer.

 

lol

 

Someone doesn't get it.

By the time the air moving under the car gets to the rear bumper it's so turbulent that cutting holes in your bumper won't make any difference whatsoever. Not to mention that all cars with legitimate rear diffusers have some sort of underbody venturi. You can't have one component of a system and expect it to work as well as a whole.

 

Great, so who makes an underbody venturi?
