A rear diffuser is point less on a sn95 stang unless you want it for looks only.
The cars underbody is in no way designed for aerodynamic purposes.
Only way it would work is be creating your own underpanels that would cover the engine, driveline and rearend gas tank.
If you did do this then you prob would want to add hood vents to release under hood heat and a transmission oil cooler, and possibly a differential oil cooler ala 2000 cobra r.
I have always thought about wanting to create somthing like this. not only would it help high speed stability but could increase highway gas mileage by a mpg or two.

That sounds a lot like what me and Pete thought up yesterday, the part about it being completely useless performancewise. Its got an interesting look but without the rest of the underpanels its pretty useless

Didn't I say all of that in my first post in this thread? Haha.

Haha, I just wanted to take credit for sounding smart for once... Arin, we should completely aero-ify my car. 
It would just take a hell of a lot of fiber glass...

A few people drill multiple holes in the rear bumper of their sn95s to help. That is the closest thing to a rear diffuser I have seen on one of these cars. Also, all of the cars that had this done were flat out drag cars.

Yeah, for me this would just be a fun project, not a real aero enhancement. Aluminum, I would assume, is much more expensive, isn't it?

Aw, crap. Are you serious about the additional underpanels? I hadn't heard about that before. I was under the impression that a properly done rear diffuser would infact have an aid in the overall performance of the vehicle becuase it would decelerate the the flow of air going under the car so that iot would be at the same relative speed as the air around the car.

Well, I think I'm just going to drop it. I figured it would probably help overall with the Steeda front splitter I was thinking of putting on the front.

Like I said before, it can't hurt to add it, but there will be no significant changes without adding underbody modifications.

I saw that when I was looking around for one, and I really don't think it flows with the car whatsoever. I'm hoping that what I'm thinking of, since it will be molded into the bumper cover itself, will have a nice flow to it as well as having a positive effect on how it looks.
