I think people throw the term "diffuser" around very lightly. I highly doubt that Ford made the OEM Boss part as an actual diffuser. It appears to be just a styling part.

It actually does work, in conjuction with all of the other parts, however.

I wish they made the rear diffuser a little more aggressive on the Laguna Secs models, much like that front splitter. If they did, I would have that combo on my car immediately.

Seems so unnecessary to custom build one for a daily driver.
How unstable is your car at speeds?

There is no way that boss 302 rear diffuser is functional.

Correct.

Well, this is stupid

No fucks given. It's something I wanna do. I've already asked josh for some insight on materials. Like I said if I change my mind I can buy a Boss 302 Diffuser and blend in with the crowd.

I applaud the desire to make something unique using your own skills and talent.

But I sure hope it doesn't look as obnoxious as the examples you showed. I'll withhold judgment until we actually see the finished piece. Who knows, you might come up with something totally badass that we'll all line up to buy. Good luck man.

Thanks. These pictures are an extreme version. What I would like to do is makwe it somewhere in the middle. An enhanced version of the Boss one if you will. Just extended and improved.
