Rear Diffuser

[Ravage]

Had an opportunity to follow someone with the Stillen version. Man, those things were really flapping back and forth.

I have the Stillens and pics I've seen of them while underway, they do move around.

Were these the extended ones?

Mine are longer than stock

My stillens were stock length. There was a choice to order

Michael-does it look like a horse flapping it's lips? In which case I'll put the stock one on.

LOL, No, not like horse lips

I’ve been told by reliable source who worked on the program that the Stillen ones aren’t firm enough to be functional at high speed.
Perhaps you can order a new one through your local Ford dealer?

If you plan to run the Mile or realy high speed tracks, use the OE diffuser. If you just want to save your OE diffuser and drive on the street at quasi-legal speeds, the Stillen is fine. The diffuser doesn't produce appreciable aerodynamic effect until you are well into triple digits.

Maybe if you're shooting for 200mph+ at the Texas mile but for street and most casual weekend trackers they're find. Noone spotted mine.

I had the CF ones made by a company in the Phoenix AZ area. Stout & beautiful.

As others have stated these just don't look right on a bumper delete car.

Ravage - Awesome wheels! Do you happen to have the model / specs / details about them? Thank you. (I tried to message you but the site says I can't)

Perhaps part of the bumper delete includes a repositioning of the rear diffuser. Rich and GT guys did mine and it's clearly different.

Finally found my pic of OEM and Stillen

You got the long ones. There is a version that is the same size.

Anybody done a repaint of the under trays ?

I would love to have the paint code for that greenish/brown/black coating.
