Extra set of Stillen Diffusers for sale

Hi all

I ordered the Stillen diffusers and from all the descriptions it looked like they were singles and fit either side so I ordered two. It turns out that it is a pair so I have two full sets.

Stillen would charge me a restocking fee and return shipping to return one unopened box, so I'd offer to send the extra here to anyone for the Stillen price which is roughly $325 for the pair with shipping included.

These are the standard OEM sized diffusers (Stillen also has an extended length). The kit includes instructions and replacement rivets and the units include divets where to drill out to match up to the holes in the belly pan.

I assume that everyone is familiar with the diffusers and that they individual parts cannot be ordered from Ford, and that the entire belly pan has to be replaced at a cost of $1000+. The Stillen replacements are made from a more forgiving material although still pretty stout.

Anyone interested PM me. I have a couple of weeks before I have to return them to Stillen.

Cheers!

So cool to follow cars fitted with these, at certain speeds the airflow makes them wiggle back and forth like they’re waving at you!
 
Yeah, they're not rigid. But they are very forgiving. One of the loudest noises I ever heard in my GT was when the stock diffuser hit a parking curb.
 
Would be interesting to know if they have the same aerodynamic performance with that much flex.
 
Are the OEM sized Stillen made diffusers, the same shape, just a more flexible material?

you are correct they do not
 
But they look really good!
 
I'm told that the originals can be repaired, but I could never find anyone that was willing to undertake the task with any degree of certainty.

We did something like this. Can't even find the area I fixed.
 
My paint/body guy also repaired a cracked fin on mine (with some sort of putty/epoxy/?) about a year ago...and you cannot tell (even when its on the lift at eye level.
