One issue with the Crossfire air flow is the retro design of the rear. According to Eric Stoddard the spoiler was installed to reduce the induced lift. That suggests a significant aerodynammic negative force on the vehicle'smovement thru the air.

I'm gonna go out on a limb here and also suggest the Roadster has this issue more than the coupe.

I would think the compressed air coming under the car could be utilized to throw air and salt spray up on the back bumper. And thereby reduce the low pressure hole created at the back of the car.
Is there any advantage to using a diffuser baffle? High or low?

I would think Woody would have some interesting and likely useful ideas on this. How about it Woody?
